1. Out of the Box

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the EV-INVERTER reference platform.

1.1 Kit Contents and Packing List

The EV-INVERTER kit contents include:

  • Driver control board (EV-POWEREVB)
  • MCU control board (EV-CONTROLEVM)
  • Sensor board (EV-SENSOREVB)
  • Interface board (EV-INTERFACEVB)
  • Cables (EV-HW-INVERTER)
    • –Cable assembly, double row wire cable, socket, double ended, 2×20, with retention latch, 4" length
    • –Cable assembly, double row wire cable, socket, double ended, 2×15, with retention latch, 5.5" length
    • –Cable assembly, double row wire cable, socket, double ended, 2×5, with retention latch, 4" length
  • Quick start guide (HV Inverter platform)

1.2 Additional Hardware

In addition to the kit contents, the following hardware is necessary or beneficial when working with this reference platform. A complete EV Inverter Platform can be purchased from our development partner Vepco Technologies.

  • FujiIGBTM653 module: available for purchase from Fuji Electric, Inc. by authorized customers of the NXP EV Inverter enablement kit.
  • Cooling plate or water jacket for IGBT Fuji IGBTM653 module: the cold plate serves as the cooling structure interface for the IGBT module and it functions as mechanical support to the Power Inverter module (PIM) electronics and accessory components. Provide a cooling plate of your own design or purchase the complete platform from our inverter partner Vepco Technologies.
  • DC link capacitor: four EZP-E50117MTA 500 V 110 µF film capacitors connected in parallel are used for inverter baseline performance measurements. Selected capacitor must be compatible with the IGBT listed above and intended operating voltages.
  • Busbar: provide your own design or available when purchasing the complete platform from Vepco Technologies.
  • High-voltage cabling: provide your own or available when purchasing the complete platform from Vepco Technologies
  • 23-position signal connector: (Ampseal®PN 770680-1) TEConnectivity-770680-1
  • Mounting hardware: provide your own or available when purchasing the complete platform from Vepco Technologies
  • Power supply: up to 500 V, 400 A
  • CAN interface link
  • Motor: provide your own or available from Vepco Technologies

2.2 Board Description

The EV-INVERTER is a reference design enablement kit containing NXP content to develop an EV three-phase traction motor inverter. The system is designed to drive the Fuji M653 IGBT module. This kit includes four PCBs as described in Section 1.1 "Kit contents/packing list", three cables used to interconnect the PCBs and basic configuration and drive software. PCB board layout and schematics and gerber files are available at EV Power Inverter Platform.

It is your responsibility to obtain the additional inverter components. These components include the IGBT module, link capacitor, bus bar, cooling plate, mounting hardware, etc.

You can design, select and assemble your own components and use the NXP PCBs to complete a PIM. A complete pre-assembled reference PIM platform is available through our partner Vepco Technologies. The IGBT module is available from our partner Fuji Electric.

3. Configure Hardware

3.1 Configure the Hardware

To configure the hardware, complete the following procedure:

  1. Attach the IGBT module to the cooling plate
  2. Attach the DC link capacitor positive and negative high-voltage supply
  3. Attach the EV-POWEREVB to the IGBT module. Ensure that all board socket connection pins are properly seated onto the IGBT pin connections
  4. Connect the motor to the IGBT module, ensuring the U, V, and W connections match
  5. For running a motor in a closed loop motor control, connect the EV-SENSOREVB board to the EV-CONTROLEVM
  6. Connect the EV-POWEREVB to the EV-CONTROLEVM
  7. Connect the EV-INTERFACEVB to the EV-CONTROLEVM
  8. Connect the low-voltage DC power supply to the EV-CONTROLEVM board
  9. Connect the high voltage/high current DC supply positive and negative connections on the DC Link capacitor to supply three-phase motor DC link voltage
  10. Before applying high voltage (>300 V) to the DC connection, use a current limited (1.0 A) power supply and apply 15 to 30 V to the DC to make sure that there is no excessive leakage current
  11. Unlatch the handle, insert the cable assembly to the header and relatch the handle. 12.Connect the EXT_DGND to 12 V GND
  12. Open the PIM by removing the plastic protection cover
  13. Connect the 14-pin debugger header with pin 1 mark aligned
  14. Both LED lights on the P&E micro Multilink should be On
