A motor-generator system mainly performs motor control to provide motive power and also controls regeneration via the motor acting as a generator. Advances aimed at lower fuel consumption and reduced CO2 emissions are being made constantly in motor and regeneration control, and they require microcontrollers (MCUs) with high performance and advanced functions.
In response to these demands, Renesas offers an extensive lineup of MCUs that incorporate high-performance CPUs, timers and ADC functions ideal for motor and regeneration control, and resolver/digital converters (RDCs) for a further reduction in system cost. We also supply analog and power devices suitable for motor-generator systems.
Better system performance and a more compact size can be achieved using a Renesas MCU equipped with functions optimal for HV/EV control.
Motor Control IP (EMU)
- Perform feedback control of a motor using dedicated hardware, and motor control without a CPU (software)
- Vastly reduce CPU processing load and realize high-speed rotation
- Basic hardware control, although software processing can also be inserted mid-control according to the customer's specifications
- Can adjust fine operation gain using variable parameter settings
Resolver/Digital Converter (RDC)
- Dedicated IP that processes complicated analog signals from a motor rotational angle sensor (resolver)
- Port Tamagawa Seiki's proven RDC to Renesas' state-of-the-art process
- More compact system size
- Improved noise tolerance, reliability and precision
