2.2 Board Description

The EV-INVERTERHDBT is a reference design IGBT enablement kit containing NXP content to develop an EV three-phase traction motor inverter. The system is designed to drive an IGBT with equivalent P6 footprint HybridPACK pin out and form factor. This kit includes two PCBs, 3-phase bus bars and basic configuration and enablement software. PCB board layout, schematics and Gerber files are available on an NXP secured website. To gain access to the secured site, use the registration code provided in the hardware shipment.

Customers must obtain the additional inverter components. These components include the IGBT module, link capacitor, bus bar, cooling plate, mounting hardware, etc. Customers can select their own components when designing and assembling a complete PIM to work with the NXP EV-CONTROLEVMHD and EV-POWEREVBHDBT boards. As an alternative, a complete pre-assembled reference PIM platform is available through NXP partner Vepco Technologies.

The procedure for assembling an inverter platform that uses the EV-INVERTERHDBT IGBT enablement kit differs depending on whether the Vepco PIM is employed or whether the customer has chosen to configure their own platform. The following sections cover both procedures.

3.1 Assemble the Hardware (Vepco Procedure)

The assembly instructions in this section apply to users who have elected to use the Vepco PIM.

The following hardware is required for this procedure:

• Vepco Power Inverter Module (PIM)
• High-voltage cabling for inverter supply (2-wire)
• High-voltage cabling for motor connection (3-wire)
• 12 V power supply (inverter)
• High-voltage power supply (motor)
• Motor
• PEMicro Multilink debugger probe
• Kvaser Leaf Light v2 USB – CAN interface adapter

Figure 4. Assembly procedure using the Vepco PIM with the EV-INVERTERHDBT IGBT enablement kit

1. Turn the Vepco PIM upside down and remove the bottom plate. This exposes the EV- CONTROLEVMHD board mounted inside the unit.
2. Connect the 14-pin PEMicro Multilink debugger header to connector P1 on the EV- CONTROLEVMHD with the pin 1 marks aligned. Connect a USB cable from the PEMicro Multilink to the host PC. Both LED lights on the PEmicro Multilink should be on, indicating the CAN bus is live and ready to communicate. For information on installing the PEMicro software and debugging with the PEMicro probe, see PEMicro documentation.
3. Route the Kvaser Leaf Light USB-CAN Interface Adapter from the 23-pin connector on the bottom of the EV-CONTROLEVMHD board to a USB port on the Windows PC.
4. Install the software development tools.
5. Follow the instructions in the Vepco PIM documentation to make the following connections:
   • 3-phase motor
   • Low-voltage DC power supply
   • High-voltage DC power supply. Warning: HIGH DC VOLTAGES CAN BE FATAL. Use extreme caution.

3.2 Assemble the Hardware (Non-Vepco Procedure)

The following assembly instructions apply to users who have elected to design their own inverter control platform instead of using the Vepco module. The instructions cover electrical connectivity only. The customer is responsible for assembling the physical structures (bus bar, mounting hardware, etc.) required to support and connect the components in their platform.

Figure 5. Assembly procedure using the EV-INVERTERHDBT IGBT enablement kit with a non-Vepco P6 footprint IGBT module

1. Attach the IGBT module to the cooling plate.
2. Attach the DC link capacitors to the bus bar.
3. Connect the three positive power connectors on the IGBT module to the corresponding connectors on the bus bar. Connect the three negative power connectors on the IGBT module to the corresponding connectors on the bus bar.
4. Connect output phase bus bars to the three output connectors on the IGBT module with the screws provided in the kit. Then, route each bus bar through one of the three motor phase current sensors(U21, U22, U23) on the EV-CONTROLEVMHD board.
5. Connect the 3-phase motor by drawing high voltage cables from the three output phase bus bars that were routed through the current sensors in the previous step. Make sure that the U, V and W connections match. Secure the connection with the screws provided in the kit and ensure that the plastic caps are placed on top of the screws.
6. Connect the motor resolver to the 23-pin connector on the EV-CONTROLEVMHD board (refer to EV-CONTROLEVMHD board schematics). The connections are made as follows:
   • Using the two-wire high-power shielded cable, connect pin 14 and pin 21 (resolver excitation signals) on the 23-pin connector to the corresponding connections on the motor. Connect the shield ground to pin 6 on the 23-pin connector
   • Using the low-power cable, connect pins 8, 15, 22, and 23 (resolver sense signals) on the 23-pin connector to the corresponding connections on the motor. Connect the shield ground to pin 7 on the 23-pin connector
   • Using the low-power cable, make all remaining connections (CANH, CANL, etc.)
   • Connect the EXT_DGND to 12 V GND
7. Connect the two enablement kit boards. The connection can be made using two different methods:
   • Method A: Mount the EV-CONTROLEVMHD board on top of the EV- POWEREVBHDBT board by directly connecting the 40-pin connectors (J1 and P1) and the +12 supply connectors (P6 and P2). Make sure that the pins on the lower board are inserted into the connectors on the upper board. Use stand-offs to provide structural support between the two boards. Notice that connecting the boards in this fashion blocks access to the test points and components on the top of the EV- POWEREVBHDBT board
   • Method B: Connect the two boards with cables. To do so, connect a 40-pin ribbon cable between connector J1 on the EV-CONTROLEVMHDBT board and connector P1 on the EV-POWEREVBHDBT board. In this configuration, the EV-POWEREVBHDBT board must be powered independently from the EV- CONTROLEVMHD board (see step 9)
8. Connect the EV-POWEREVBHDBT board to the IGBT module. This is best done by aligning the pins on the surface of the IGBT module with the IGBT module connectors on the bottom of the EV-POWEREVBHDBT board and mounting the two units together. Alternatively, each of the pins on the PC module can be wired to the corresponding connector on the EV-POWEREVBHDBT board.
9. Connect the low-voltage DC power supply (12 V) to connector P6 on the EV- CONTROLEVMHD board. If Method B in Step 6 was used to connect the EV- CONTROLEVMHD board to the EV-POWEREVBHDBT board, an additional connection must be made from the low-voltage DC power supply to the +12 Supply connector (P2) on the EV-POWEREVBHDBT board. When the two boards are mounted, as in Method A, Step 7, the EV-POWEREVBHDBT draws power directly through the +12 Supply connector on the EV-CONTROLEVMHD board.
10. Using the 2-wire high-voltage cable, connect the positive connector on the high- voltage/high-current DC supply to the positive DC link capacitor connectors on bus bar. Then connect the negative connector on the high-voltage/high current DC supply to the negative DC link capacitor connectors on the bus bar. Warning: HIGH DC VOLTAGES CAN BE FATAL. Use extreme caution. Before applying high voltage (>300 V) to the DC connection, use a current limited (1.0 A) power supply and apply 15 V to 30 V to the DC to make sure that there is no excessive leakage current.

11. Connect the 14-pin PEMicro Multilink debugger header to connector P4 on the EV-CONTROLEVMHD with the pin 1 marks aligned. Connect a USB cable from the PEMicro Multilink to the host PC. Both LED lights on the PEmicro Multilink should be on, indicating that the JTAG bus is live and ready to communicate. For information on installing the PEMicro software and debugging with the PEMicro probe, see PEMicro documentation.
12. Attach the Kvaser Leaf Light USB-CAN Interface Adapter to the 23-pin connector on the bottom of the EV-CONTROLEVMHD board and a USB port on Windows PC.
13. Install the software development tools.
