Unit in Power Limit or in Current Limit:
Control and Status
The Rectifier provides three means for monitor/control:
analog, PMBus™, or the GE Galaxy-based RS485 protocol.
Details of analog control and the PMBus™ based protocol are
provided in this data sheet. GE will provide separate
application notes on the Galaxy RS485 based protocol for
users to interface to the rectifier. Contact your local GE
representative for details.
Control hierarchy: Some features, such as output voltage, can
be controlled both through hardware and firmware. For
example, the output voltage is controlled both by a signal pin
(Vprog) and firmware (Vout_command, 0x21).
Using output voltage as an example, the Vprog signal pin
voltage level sets the output voltage if its value is
between 0.1 and 3.0 VDC (see the “Voltage programming”
section). When the programming signal Vprog is either a noconnect (0V) or > 3VDC, the output voltage is set at the default
value of 52VDC.
The signal pin controls the corresponding feature until the
firmware command is executed. Once the firmware command
has been executed, the signal pin is ignored until input power
is removed and reapplied, which resets control to the signal
pin. In the above example, the rectifier will no longer ‘listen’
to the Vprog pin after Vout_command has been executed, as
long as input power is applied without interruption.
In summary, hardware signals such as Vprog are utilized for
setting the initial default value and for varying the value until
firmware based control takes over. Once firmware control is
executed, hardware based control is relinquished so the
processor can clearly decide who has control.
Analog controls: Details of analog controls are provided in
this data sheet under Feature Specifications.
Signal Reference: Unless otherwise noted, all signals are
referenced to LGND (“Logic Ground”). See the Signal
Definitions Table at the end of this document for further
description of all the signals.
LGND is isolated from the main output of the rectifier for
PMBus communications. Communications and the 5V standby
output are not connected to main power return (Vout(-)) and
can be tied to the system digital ground point selected by the
user. (Note that RS485 communications is referenced to
Vout(-), main power return of the rectifier).
LGND is capacitively coupled to Earth Ground inside the
rectifier where Earth Ground is also wired to the metal case).
The maximum voltage differential between LGND and Earth
Ground should be less than 100VDC.
Delayed overcurrent shutdown during startup: Rectifiers are
programmed to stay in a constant current state for up to 20
seconds during power up. This delay has been introduced to
permit the orderly application of input power to a subset of
paralleled front-ends during power up. If the overload persists
beyond the 20 second delay, the front-end will revert back
into its programmed state of overload protection.
September 1, 2021
When output voltage
is > 10VDC the Output LED will continue blinking.
When output voltage is < 10VDC, if the unit is in the RESTART
mode, it goes into hiccup. When the unit is ON the output LED
is ON, when the unit is OFF the output LED is OFF.
When the unit is in latched shutdown the output LED is OFF.
Auto restart: Auto-restart is the default configuration for
over-current and over-temperature shutdowns. These
features are configured by the PMBus™ fault_response
commands
An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute
less than 3 shutdowns occurred then the count for latch OFF
resets and the 1 minute window starts all over again.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the rectifier to remain latched off
for over_temperature and over_current.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via i2c
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
Each of these commands must keep the rectifier in the OFF
state for at least 2 seconds, with the exception of changing to
restart.
A successful restart shall clear all alarm registers, set the
restarted successful bit of the Status_2 register.
A power system that is comprised of a number of rectifiers
could have difficulty restarting after a shutdown event
because of the non-synchronized behavior of the individual
rectifiers. Implementing the latch-off mechanism permits a
synchronized restart that guarantees the simultaneous restart
of the entire system.
A synchronous restart can be implemented by;
1. Issuing a GLOBAL OFF and then ON command to all
rectifiers,
2. Toggling Off and then ON the ON/OFF (ENABLE) signal
3. Removing and reapplying input commercial power to the
entire system.
The rectifiers should be turned OFF for at least 20 – 30
seconds in order to discharge all internal bias supplies and
reset the soft start circuitry of the individual rectifiers.
Control Signals
Protocol: This signal pin defines the communications mode
setting of the rectifier. Two different states can be configured:

Address detection: The Slot_ID pin must be connected to
Vout(-) in order to deliver output power. This connection
provides a second interlock feature. This connection may be a
short circuit or any resistance up to 100 kohm, to allow
addressing in RS485 mode as described below.
September 1, 2021
Global Broadcast: This is a powerful command because it
instruct all rectifiers to respond simultaneously. A read
instruction should never be accessed globally. The rectifier
should issue an ‘invalid command’ state if a ‘read’ is
attempted globally.
For example, changing the ‘system’ output voltage requires
the global broadcast so that all paralleled rectifiers change
their output simultaneously. This command can also turn OFF
the ‘main’ output or turn ON the ‘main’ output of all rectifiers
simultaneously. Unfortunately, this command does have a
side effect. Only a single rectifier needs to pull down the ninth
acknowledge bit. To be certain that each rectifier responded
to the global instruction, a READ instruction should be
executed to each rectifier to verify that the command
properly executed. The GLOBAL BROADCAST command should
only be executed for write instructions to slave devices.

Alert Response Address (ARA): This feature enables the
‘master’ to rapidly determine which ‘slave’ rectifier triggered
the Alert# signal without having to poll each rectifier one at a
time. During normal operation the rectifier activates (pulls
down LO) the Alert# signal line indicating that it needs
attention when a ‘state’ change occurs. The master can
determine who pulled the ‘alert’ line by sending out the alertresponse-address, address 12b, with a ‘read’ instruction. If the
rectifier triggered the ‘alert’ it should respond back with its
address. The instruction takes the form below;

S

ARA address
Rd

My
address

PEC
A
P
If during the ARA response multiple rectifiers send out their
addresses, then the actual address received by the master is
the lowest address from the combinations of those rectifiers
that responded.
The ‘my address’ field contains the address of the rectifier in
the 7 most significant bits (msb) of the byte. The lsb of the
byte is a don’t care, it could be a 0 or a 1. For more
information refer to the SMBus specification
The µC needs to read the actual my address data byte that is
sent back to the master. If the my address data byte agrees
with the address of this unit, then, and only then, the µC
needs to clear (de-assert) its Alert# signal. Thus, the rectifier
whose address has been sent out gets de-asserted from the
joint Alert# line.
If the Alert# line is still asserted, the host should send out an
ARA request again and find out who else asserted Alert#. This
process needs to continue until the Alert# is released which is
a clear indication that all rectifiers that asserted Alert# have
had their status states read back.
Voltage programming (Vprog): Hardware voltage
programming controls the output voltage until a software
command to change the output voltage is executed. Then
software voltage programming overrides the hardware margin
setting and the rectifier no longer listens to any hardware
margin settings until power to the controller is interrupted,
for example if input power or bias power is cycled off, then
on.
Under hardware voltage programming, an analog voltage on
Vprog can vary the output voltage linearly from 18Vdc to
53Vdc (FB version) or 18Vdc to 58Vdc (FB2 version) for 0.1V ≤
Vprog ≤ 3.0V referenced to LGND. If Vprog is raised ≥3.2V,
Vout is reset to its default value of 52V. If 0 ≤ Vprog 10A, a fault is issued.

Command Execution: The master not in control can issue two
commands on the bus, take_over_bus_control and
clear_faults
Take_over_Bus_Control(0xD8): This command instructs the
internal µC to switch command control over to the ‘master’
that initiated the request.
Actual transfer is controlled by the I2C selector section of the
µC. A bus transfer only occurs during an idle state when the
‘master’ currently in control (in the execution process of a
control command) has released the bus by issuing a STOP
command. Control can be transferred at any time if the
‘master’ being released is executing a read instruction that
does not affect the transfer of command control. Note; The
µC can handle read instructions from both busses
simultaneously.
The command follows PMBus™ standards and it is not
executed until the trailing PEC is validated.
Status Notifications: Once control is transferred both Alert#
lines should get asserted by the I2C selector section of the µC.
The released ‘master’ is notified that a STATUS change
occurred and he is no longer in control. The connected
‘master’ is notified that he is in control and he can issue
commands to the rectifier. Each master must issue a
clear_faults command to clear his Alert# signal.
If the Alert# signal was actually triggered by the rectifier and
not the I2C selector section of the µC, then only the ‘master’ in
control can clear the rectifier registers.
Incomplete transmissions should not occur on either bus.
General performance descriptions
Default state: Rectifiers are programmed in the default state
to automatically restart after a shutdown has occurred. The
default state can be reconfigured by changing non-volatile
memory (Store_user_code).
Delayed overcurrent shutdown during startup: Rectifiers are
programmed to stay in a constant current state for up to 20
seconds during power up. This delay has been introduced to
September 1, 2021
permit the orderly application of input power to a subset of
paralleled rectifiers during power up. If the overload persists
beyond the 20 second delay, the rectifier will revert back into
its programmed state of overload protection.
Unit in Power Limit or in Current Limit: When output voltage
is > 36VDC the Output LED will continue blinking.
When output voltage is < 36VDC, if the unit is in the RESTART
mode, it goes into hiccup. When the unit is ON the output LED
is ON, when the unit is OFF the output LED is OFF.
When the unit is in latched shutdown the output LED is OFF.
Restart after a latchoff: PMBus™ fault_response commands
can be configured to direct the rectifier to remain latched off
for over_voltage, over_temperature and over_current.
To restart after a latch off either of five restart mechanisms
are available.
1. The hardware pin ON/OFF may be cycled OFF and
then ON.
2. The unit may be commanded to restart via i2c
through the Operation command by cycling the
output OFF followed by ON.
3. Remove and reinsert the unit.
4. Turn OFF and then turn ON AC power to the unit.
5. Changing firmware from latch off to restart.
Each of these commands must keep the rectifier in the OFF
state for at least 2 seconds, with the exception of changing to
restart.
A successful restart shall clear all alarm registers, set the
restarted successful bit of the Status_2 register.
A power system that is comprised of a number of rectifiers
could have difficulty restarting after a shutdown event
because of the non-synchronized behavior of the individual
rectifiers. Implementing the latch-off mechanism permits a
synchronized restart that guarantees the simultaneous restart
of the entire system.
A synchronous restart can be implemented by;
1. Issuing a GLOBAL OFF and then ON command to all
rectifiers,
2 . Toggling Off and then ON the ON/OFF (ENABLE) signal
3. Removing and reapplying input commercial power to the
entire system.
The rectifiers should be turned OFF for at least 20 – 30
seconds in order to discharge all internal bias supplies and
reset the soft start circuitry of the individual rectifiers.
Auto_restart: Auto-restart is the default configuration for
over-current and over-temperature shutdowns. These
features are configured by the PMBus™ fault_response
commands
An overvoltage shutdown is followed by three attempted
restarts, each restart delayed 1 second, within a 1 minute
window. If within the 1 minute window three attempted
restarts failed, the unit will latch OFF. If within the 1 minute

less than 3 shutdowns occurred then the count for latch OFF
resets and the 1 minute window starts all over again
•
Fault Management
The rectifier recognizes that certain transitionary states can
occur before a final state is reached. The STATUS and ALARM
registers will not be frozen into a notification state until the
final state is reached. Once a final state is reached the Alert#
signal is set and the STATUS and ALARM registers will not get
reinstated until a clear_faults is issued by the master. The only
exception is that additional state changes may be added to
the original list if further changes are noted.
The rectifier differentiates between internal faults that are
within the rectifier and external faults that the rectifier
protects itself from, such as overload or input voltage out of
limits. The FAULT LED, FAULT PIN or i2c alarm is not asserted
for EXTERNAL FAULTS. Every attempt is made to annunciate
External Faults. Some of these annunciations can be observed
by looking at the input LEDs. These fault categorizations are
predictive in nature and therefore there is a likelihood that a
categorization may not have been made correctly.
Input voltage out of range: The Input LED will continue
blinking as long as sufficient power is available to power the
LED. If the input voltage is completely gone the Input LED is
OFF.
State Change Definition
A state_change is an indication that an event has occurred
that the MASTER should be aware of. The following events
shall trigger a state_change;
•
Initial power-up of the system when AC gets turned ON .
This is the indication from the rectifier that it has been
turned ON. Note that the master needs to read the status
of each rectifier to reset the system_interrupt.
•
Any changes in the bit pattern of either the PMBus
standard STATUS or the mfr_specific STATUS registers
should trigger the Alert# signal.
Smart Hot plug
The wide output capability of this rectifier requires special
controls when the rectifier gets plugged into a live backplane.
During hot plug the rectifier attempts to configure itself into
the bus voltage setting of a working system. When inserted
into the system the output of the rectifier will be off.
•
•
Prior to turning ON the main output, the rectifier reads
the voltage present on the bus. If the bus voltage is ≥18V
the rectifier will check whether Vmargin and the bus
voltage are in agreement with each other.
If there is agreement between Vmargin and the bus
voltage, the rectifier will proceed to turn ON its output
September 1, 2021
•
•
utilizing the delayed overcurrent shutdown during turnON.
If there is no agreement between Vmargin and the bus
voltage, the rectifier recognizes that the bus voltage is
being controlled externally. In this case the rectifier will
keep its output OFF and will wait for the controller based
output voltage command. Once such a command is
received from the controller, the rectifier will proceed
with normal turn-ON utilizing the delayed overcurrent
shutdown.
The rectifier continues vto monitor Vmargin and the bus
voltage. If no command is received from the controller,
and if Vmargin and the bus voltage should agree at a
later time, then the rectifier will normally turn ON it
output utilizing the delayed overcurrent shutdown.

Upgrade procedure
1. Initialization: To execute the re-programming/upgrade in
the system, the rectifier to be re-programmed must first
be taken OFF-line prior to executing the upgrade. If the
rectifier is not taken OFF-line by the system controller, the
boot loader will turn OFF the output prior to continuing
with the re-programming operation.
Note: Make sure that sufficient power is provided by the
remaining on-line rectifiers so that system functionality is
not jeopardized.

After completion of the first data packet upload the Boot
loader increments the sequence number. A subsequent read
to the boot loader will return the incremented sequence
number and a STATUS byte. This is a validity check to ensure
that the sequence number is properly kept. The returned
STATUS byte is the same as the application status response. It
is appended here automatically to save the execution of
another command. It should be checked to ensure that no
errors are flagged by the boot loader during the download. If
an error occurred, terminate the download load and attempt
to reprogram again.
15. Execute an Application status command to verify that
the error check is valid. The returned status should be
0x80.
16. Execute a Boot loader command to exit boot block. Upon
receipt of the command the PFC µC will transfer to the
uploaded application code.

If a transmission error occurs, or if the uC did not receive the
data from the DSP, the uC may set the length to 0, issue a PEC
and terminate the transmission.
The data array supported by rev 1.3 of the GE Interface
Adapter is 32 x 64 comprising 2048 bytes of data.
The rolling event recorder
The purpose of the black box is to provide operational
statistics as well as fault retention for diagnostics following
either recoverable or non-recoverable fault events. Sufficient
memory exists to store up to 5 time-stamped snapshot
records (pages) that include the state of the status and alarm
registers and numerous internal measurement points within
the rectifier. Each record is stored into nonvolatile memory at
the time when a black box trigger event occurs. Once five
records are stored, additional records over-write the oldest
record.
The memory locations will be cleared, when the product is
shipped from the GE factory.
Operational use statistics
This feature of the black box includes information on the
repetition and duration of certain events in order to
understand the long-term operational state of the rectifier.
The events are placed into defined buckets for further
analysis. For example; the rectifier records how long was the
output current provided in certain load ranges.
Accessing the event records
The event records are accessed by uploading the entire
contents of the black box of the rectifier into a folder assigned
by the user. Within the I2C protocol this upload is
accomplished by the upload_black_box (0xF0) command
described below. GE provides a Graphical User Interface
(GUI) that de-codes the contents of the black box into a set of
records that can be reviewed by the user.
Upload black box(0xF0): This command executes the upload
from the rectifier to a file of the user’s choice.
The 100ms delay prior to the restart is mandatory to provide
enough time for the rectifier to gather the required data from
the secondary DSP controller.

Bus transfer reporting
The events below concentrate on what happens when a clear_faults is issued. The system controller needs to be
intelligent enough to inquire the status of the power supply before issuing a clar_faults. Otherwise, it would lose

controller needs to read status before clearing the registers.
Assuming that the event has cleared
the Alert remains because of status_bus, not because of unit fault
Assuming that the event has cleared
the command is rejected because i2c0 is not in control
Rules:
Side in control is the only one that can clear the Status registers.
The side in control cannot clear the alert of the side not in control
A power supply alarm should not set the status_bus registers
Latched status states until cleared
The following bits are sticky until cleared by the customer
Or’ing test failed or passed: I cannot see how it could be otherwise. The customer needs to delete the information (clear_faults) thus
indicating that he received the information.
Restarted_ok: this bit has been removed from the requirements. PMBus latched states replace this bit.
Shutdown: must be sticky – it tells the customer that the rectifier output has been turned OFF
OV, UV, OC, input, unknown warnings & faults, CML Errors, Internal or External Fault: must be sticky
OC and OT response registers are in their own confined state. The only way these should change is by commanding the change by the
controller. So theoretically they are sticky because a clear_faults should never change them.
The way to look at this is, all fault information is sticky (if the fault still persists after a clear_faults has been issued then the fault state
will reassert), all operational state information is not sticky.

Temperature Monitoring Location
The following graphic shows the heatsink location, and heatsinks are the hot spots, should maintain the surface
temperature above these hot spots at the recommended operating temperature or below. normally, the
HS_1(monitor_1) the and the HS_2(monitor_2) are the hottest spot, so can assume these two hot spots surface
temperature (cold plate side) as the case temperature.
