Introduction
More Stringent Energy Regulations Drive Motor Control Innovations
In today’s expanding industrial marketplace, the demand for electrical power is growing at an unprecedented rate. More than 40% of that electrical
demand comes from industrial electric motors of all sizes. Because of that phenomenon, governments and certification agencies worldwide are
introducing new regulatory legislation and more stringent energy efficiency requirements on electric motor OEMs and end users. Like many great
technological innovations, there needs to be a pressing demand in the market for change.
Analog Devices recognized years ago that this new era of smarter and highly efficient motor control systems would be the new standard for the motor
control industry. As part of that recognition, ADI embarked on an integrated and comprehensive motor control design program in collaboration with our
strategic partners, who are experts in their respective fields (MathWorks,® ARM,® Boston Engineering,® IAR® systems, and Xilinx®), aimed at addressing the
entire system architecture to achieve the greatest level of efficiency while improving system accuracy and reliability.
By taking a system-level view (see Figure 1) of these new challenges, ADI was able to develop products that not only exceeded the individual
performance specifications but also represented the optimal interface between other functional blocks of the circuit. This system solution approach
enables ADI to offer industrial-based customers a completely integrated solution that fits their specific needs while helping them meet the new, more
stringent energy regulations.

Isolated Gate Drivers
Overcoming Limitations of Optocouplers and High Voltage Gate Driver Solutions
Isolated gate drivers provide electrical isolation as well as strong gate drive capability, which is often required for safety and robustness in many system architectures.
The isolated gate driver portfolio from Analog Devices offers designers performance
and reliability advantages over designs utilizing optocouplers or pulse transformers.
Utilizing ADI’s proven iCoupler® technology, the isolated gate driver family offers the
advantage of a maximum propagation delay of 50 ns, less than 5 ns channel-tochannel matching, a 50-year lifetime for 400 V rms working voltage, and galvanic
isolation in a single package.

Power Management
Digital Power Factor Correction with PMBus for Motor Control Systems
Motor control systems are increasingly migrating from passive harmonic
correction inductors to active power factor correction ( PFC) systems to
improve total harmonic distortion (THD), reduce system size and weight,
and improve efficiency of single-phase and 3-phase designs.
The ADP1047 and ADP1048 digital power factor correction series offer
versatile controllers with input power metering capability to ±1% accuracy.
The ADP1047 is a single-phase device, while the ADP1048 is an interleaved
controller that can also be configured as a bridgeless PFC for high system
efficiency. The ADP1047/ADP1048 can be programmed using the easy
to use graphic user interface (GUI ) with programming implementation in
hardware state machine for robust and reliable motor control PFC solutions.
The PMBus™ interface allows parameters to be adjusted and reported,
including the accurate measurement of input voltage, current, power, and
temperature. The ADP1047/ADP1048 PFC family can communicate with
motor controllers, such as ADSP-CM408F, to optimize efficiency and motor
control system performance.

Current Sense Amplifiers
Current sense amplifiers are used when a shunt resistor is placed in the high side or low side and high accuracy over temperature is required in
harsh environments. In motor control, normally the bidirectional capability will be needed. In order to build fast and accurate control loops, the step
response time and common-mode voltage step immunity are critical.

Difference Amplifiers
Difference amplifiers can be used for voltage and current sensing in motor control systems because they can reject very high common-mode voltage. They
will enable the low voltage converters to interface with the high voltage industrial environment. This is especially true when functional isolation is needed.
Excellent drift and CMRR are the advantages of ADI’s difference amplifiers.

Precision Op Amps
Precision op amps are used as signal conditioning in the motor control systems. They will be used as the sensor to ADC interface, thus the rail-to-rail input
and output in high linearity will be needed. They can also be used between the resolver-to-digital converter (RDC) and the resolver to provide high current
in high slew rate and accuracy. Wider bandwidth amplifiers will be used to detect the fast changing current in the system.

design environment that enables developers to use a single model of their
entire system for data analysis, model visualization, testing, validation, and
eventually product deployment. Once the model is built and tested, accurate
real-time software is automatically generated, saving time and reducing
overall development costs as compared to traditional manual coding. Modelbased design with automatic code generation can also be used in rapid
prototyping, further reducing the design cycle. By its nature, model-based
design provides a structure for software reuse that permits established
designs to be effectively scaled up or down in complexity depending upon
the desired application and reliably upgraded in a more simplistic and costeffective manner.

Model-based design saves valuable design resources by cutting design time and providing final designs that are more accurate and
more closely approximate predesign expectations for performance, systems functionality, and features and schedule. It provides:
