EV-INVERTERHD

Roll over image to zoom in

This automotive SiC MOSFET-based EV power inverter control reference platform targets ISO 26262 ASIL D applications, such as electric vehicle traction motors.

NXP offers the choice of three tools to speed development of your inverter:

  • NXP SiC enablement kit, designed to drive SiC MOSFETs packaged in industry standard HybridPACK™ module footprint supplied by several vendors such as StarPower P6 modules using Cree SiC die, ON Semiconductor VE-Trac™ IGBT modules and Infineon IGBT modules. This kit contains two boards, basic software, functional safety concept and operation manuals described in technical and functional specifications below. External components such as the SiC module, link capacitor, bus bar and cooling plate must be supplied by the customer.
  • The enablement kit above plus functional safety software.
  • A complete inverter control reference platform available through Vepco Technologies Inc. It includes the control and power boards, StarPower P6 module using Cree SiC MOSFETs, DC link capacitor, bus bar, cooling plate, motor options, case and software.

These tools combine the NXP comprehensive automotive portfolio of world-class automotive MCUs, CAN bus and Ethernet interfaces, safety system basis chips (SBC) and high-voltage isolated SiC/IGBT gate driver IC devices. This pre-engineered platform demonstrates our focus to help you design the next generation of hybrid and electric vehicles with greater speed and less development risk.

Features

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.
