Motor-Generator Control System

详情介绍

Overview

A motor-generator system mainly performs motor control to provide motive power and also controls regeneration by 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 MCUs with high performance and advanced functions.
Renesas responds to this demand with an extensive lineup of MCUs incorporating high-performance CPUs, timers and ADC functions ideal for motor and regeneration control, and RDCs for a further reduction in system cost. We also supply analog and power devices suitable for motor-generator systems.

Achieve Better System Performance and More Compact Size Using Renesas MCU Equipped with Functions Optimal for HV/EV Control

Motor Control IP (EMU)

  • Perform feedback control of motor using dedicated hardware, and motor control without CPU (software)
  • Vastly reduce CPU processing load and realize high-speed rotation
  • Basically hardware control, although software processing can also be inserted mid-control according to the customer's specifications
  • Can adjust fine operation gain and so on 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
  • Improve noise tolerance, reliability, and precision
