描述
This traction motor controller is used to drive motor control for HEV/EV-based applications and consists of two boards: the controller board, which controls the motor driver, and digital and analog sections, and the power board, which includes power MOSFETs for motor drive. The controller board controls and drives each phase of the motor windings in the power board through the MOSFET pre-driver stage ISL78434.
The traction motor controller includes the RH850/C1M-A1 microcontroller, which is equipped with an RH850 Family G3MH CPU core operating at a frequency of 240MHz, providing high processing power. Along with the ROM, RAM, and DMA, it includes various timers such as a motor control timer, various serial interfaces including CAN (CAN FD compatible), a 12-bit A/D converter (ADC), an R/D converter (RDC3A) that converts the resolver output signal to digital angle data, and a CPU and parallel motor control unit (EMU3), etc., providing peripheral functions that are ideal for motor control in HEVs/EVs.
The controller board has three ISL78434 MOSFET pre-driver stages and μPC1251A op amps for analog and fault generation circuits, PMIC, LDO, and a power MOSFET board with RBAZ25N10CHPF. The power will be 5KW continuous power and 8kW peak power. The number of MOSFETs per phase shall be defined accordingly to the necessary load dump protection.
特性
- The MCU in the controller board interacts with external peripherals through System I/O connectors (COM, ANA, and DIO), which carry several communication interfaces, analog, and digital I/O signals
- Includes Intelligent Power Devices (IPD) for additional loads
- Implements protective functions for overcurrent, overvoltage, undervoltage, and overtemperature (controller and motor)
- Integrated interfaces such as CAN FD, LIN, SENT, isolated UART, etc.
