Safety precautions
Note:
Please note the following warnings regarding the hazards associated with development systems.
Table 1
Safety precautions
Warning: The DC link potential of this board is up to 1000 VDC. When measuring
voltage waveforms by oscilloscope, high voltage differential probes must be used.
Failure to do so may result in personal injury or death.
Warning: The evaluation or reference board contains DC bus capacitors which take
time to discharge after removal of the main supply. Before working on the drive
system, wait five minutes for capacitors to discharge to safe voltage levels. Failure to
do so may result in personal injury or death. Darkened display LEDs are not an
indication that capacitors have discharged to safe voltage levels.
Warning: The evaluation or reference board is connected to the grid input during
testing. Hence, high-voltage differential probes must be used when measuring voltage
waveforms by oscilloscope. Failure to do so may result in personal injury or death.
Darkened display LEDs are not an indication that capacitors have discharged to safe
voltage levels.
Warning: Remove or disconnect power from the drive before you disconnect or
reconnect wires, or perform maintenance work. Wait five minutes after removing
power to discharge the bus capacitors. Do not attempt to service the drive until the bus
capacitors have discharged to zero. Failure to do so may result in personal injury or
death.
Caution: The heat sink and device surfaces of the evaluation or reference board may
become hot during testing. Hence, necessary precautions are required while handling
the board. Failure to comply may cause injury.
Caution: Only personnel familiar with the drive, power electronics and associated
machinery should plan, install, commission and subsequently service the system.
Failure to comply may result in personal injury and/or equipment damage.
Caution: The evaluation or reference board contains parts and assemblies sensitive to
electrostatic discharge (ESD). Electrostatic control precautions are required when
installing, testing, servicing or repairing the assembly. Component damage may result
if ESD control procedures are not followed. If you are not familiar with electrostatic
control procedures, refer to the applicable ESD protection handbooks and guidelines.
Caution: A drive that is incorrectly applied or installed can lead to component damage
or reduction in product lifetime. Wiring or application errors such as undersizing the
motor, supplying an incorrect or inadequate AC supply, or excessive ambient
temperatures may result in system malfunction.
Caution: The evaluation or reference board is shipped with packing materials that
need to be removed prior to installation. Failure to remove all packing materials that
are unnecessary for system installation may result in overheating or abnormal
operating conditions.
Caution: EVAL-M1-IM818-A is evaluation board of IM818 series IPM and it is only default
for IM818-MCC. Don’t guarantee hardware change.

DC bus Measurement and MCEWizard configuration
Pin 14 of connector J3 provides access to the DC-link voltage. Three possible feedback cases are associated
with this pin. Figure 10 provides the DC bus sense resistor details. By default, the resistor R8 is mounted on
EVAL-M1-IM818-A.
Figure 10
DC bus sense resistor on EVAL-M1-IM818-A evaluation board
The pull-down resistor R8 of 1 MΩ referred to ground is inserted on the EVAL-M1-IM818-A evaluation board to
prevent the high BUS voltage +BUS directly connecting to the connector J3. And a pull-down resistor of 13.3 kΩ
for EVAL-M1-101T or 4.87 kΩ for EVAL-M1-183M must be inserted on the control board, and then the DCBSENSE
voltage results in the range of 0 to 3.3 V on the pin reflecting a DC bus voltage range of 0 to 800 V.

Over-current protection circuit and ITRIP signal
IM818 series provides an over-current detection function by connecting the ITRIP input with the shunt
current feedback. The ITRIP comparator threshold (typ. 0.5 V) is referenced to VSS ground.
Set D8/9/10 drop is 0.15 V, then the typical over-current threshold (IOCP) is:

PWM shut down and GK output
When over-current is detected, the ITRIP voltage is over the threshold value, then C30 will be discharged (GK
is open drain), and GK drops to “0”. This GK sends signal to control board via J3. GK “0” status is continuous
for about 150 µs. After 150 µs, GK becomes open drain and charges C30 via R20. The R20 and C30 time
constant is about 470 µs. Figure 16 shows the ITRIP and GK circuit.

The evaluation board EVAL-M1-IM818-A is general power demonstration platform with CIPOS™ Maxi IPM IM818
series. And focus on 380 VAC input, and 1~4.8 kW output application. All test date is basic on the board with
different IPM. For end user, it is only default for IM818-MCC. Other IPMs can be directly compatible and replaced
(Warning). But don’t guarantee hardware change.
Warning:
EVAL-M1-IM818-A is only default for IM818-MCC, any hardware change will not be guaranteed.
All operations can be done only when the evaluation boards has been move away from the power for over
5 minutes and double check those all capacitance voltage are lower than 5V.
Operation only for those licensed professionals under qualified safety protection （including: person，
equipment, ESD）.
For any re-install, it is necessary to clean the thermal conductive silicone grease and coating it again.

IU and IV current waveform. It is IM818-MCC work on AC380V input, PWM=6kHz, motor drive on
700rpm, Iphase=5A
Figure 33 is IPM typical switching dv/dt on “ON” and “OFF” time.
5 V/ns in switcing “ON”
Figure 33
5 V/ns in switching “OFF”
Typical dv/dt test waveform. It is IM818-MCC work on 380 VAC input at switching current is 2A.
The dv/dt is very important parameter for motor drive. This is specially set for the application.
The cable connecting the motor can be regarded as an open inductor, which forms a complete electromagnetic
radiation network with the capacitance of the motor winding to the ground. The parasitic combination emits
high-frequency electromagnetic noise to the surroundings, if there is an excitation source.

System performance
According to Fourier expansion equation, PWM square wave can be regarded as composed of several sine
waves with multiple frequencies and different initial phase angles. Changing the slope of square wave, the high
frequency harmonic components are reduced. Balance between energy efficiency and electromagnetic
compatibility by IPM design.
