Technical and Functional Specifications

Overview

  • Contains two PCB boards described below and software to drive a three-phase motor to enable quick development of your in-house inverter design using a complete NXP solution.
  • For each of the boards included in the EV-INVERTERHD enablement kit hardware schematics, PCB layout and gerber files are available for download from a secured site.

MCU Control Board
(EV-CONTROLEVMHD):

  • This board contains four key NXP integrated circuits, interface connector and current sensors. The MPC5775E is a 32-bit Power Architecture dual-core ASIL D MCU targeted for motor control, offering performance up to 264 MHz/core, CSE security, eTPU timers, software resolver and a highly scalable solution. The FS65xx system basis chip (SBC) provides power to the MCU, optimizing energy consumption and providing low voltage side monitoring and protection. The TJA1051 transceiver for high-speed CAN applications in the automotive industry provides the differential transmit and receive capability to the MPC5775E and a CAN protocol controller. As an alternative communication protocol, the TJA1100HNZ is an automotive Ethernet PHY chip with 100BASE-TI single-port PHY optimized for automotive use cases.
  • Interface connector is a 23-pin connector for motor control inputs.
  • Three LEM current sensors are incorporated on the board providing +/- 900 amp measurement range.

Driver Control Board for HD Module
(EV-POWEREVBHD):

  • • This board is designed with the StarPower P6 (HybridPACK Drive) module populated with Cree 1200V/600A 13mΩ SiC MOSFET die. It features the GD3160 advanced single-channel gate driver for IGBTs and SiC MOSFETs. Integrated galvanic isolation and low on-resistance drive transistors provide high charging and discharging current, low dynamic saturation voltage and rail-to-rail gate voltage control. The board autonomously manages severe faults and reports faults and status via INTB pin and an SPI interface. Gate voltage is supplied via isolated transformers and a flyback controller.

Basic Software Featuring:

  • Software will be provided to allow for system configuration and basic control of a three-phase inverter for driving a permanent magnetic synchronous motor (PMSM) or induction motor.
    • Low-level SDK device drivers and inverter services middleware with function calls for controlling platform motor operations.
    • Advanced AMMCLib optimized software libraries for precise motor drive control.
    • FreeMASTER graphical user interface for operating and monitoring the inverter platform.
