2.2 Board description

The RDGD3100F3PH5EVB is a fully functional three-phase inverter evaluation board populated with six GD3100 gate drivers with fault management and supporting circuitry. This board supports SPI daisy chain communication for programming and communication with three high-side gate drivers and three low-side gate drivers independently.

This board has low-voltage and high-voltage isolation in conjunction with gate drive integrated galvanic signal isolation. Other supporting features on the board include IGBT current sense and desaturation short-circuit detection, IGBT temperature sensing, DC Link bus voltage monitoring, phase current sensing, and motor resolver excitation and signal processing connection circuitry. See GD3100 data sheet for additional gate drive features.

3. Configure the hardware

To configure the hardware, complete the following procedure:

1. Assemble IGBT module with water cooling jacket if desired and properly attach to DC Link capacitor positive and negative high-voltage supply connections across U, V, and W phases.
2. Attach RDGD3100F3PH5EVB to the IGBT module. Ensure that all board socket connection pins are properly seated onto the IGBT pin connections. The board socket pins are intended for easy attachment and deattachment to IGBT module without damaging IGBT connection pins.
3. Connect motor:
   • a. Connect output of IGBT module each phase U, V, and W to each of the respective U, V, W connections on the desired three-phase motor.
   • b. For running motor in closed loop motor control, connect resolver signals from motor resolver connection to the resolver pin connections on the RDGD3100F3PH5EVB. See schematics for J2 header signal connections on the RDGD3100F3PH5EVB board.
   • c. For running motor in closed loop motor control, connect current sensors from each phase U, V, and W (current sensors are not included with RDGD3100F3PH5EVB) and connect the respective signals from the current sensors to the phase current feedback pin connections of the RDGD3100F3PH5EVB. See schematics for J1 header signal connections on the RDGD3100F3PH5EVB board.
4. Connect DC power:
   • a. Connect a low voltage DC power supply to the RDGD3100F3PH5EVB at the VSUP connection terminal (12 V DC with a minimum 1.0 A supply).
   • b. Connect a low voltage DC supply to MCU controller board and connect USB cable from MCU controller to desired computer for software driven motor control.
   • c. Connect high voltage/high current DC supply (use recommended voltage and current for desired motor) to positive and negative connections on DC Link capacitor to supply three-phase motor DC link voltage.
5. Attach 2x32 PCIe cable (S32SDEV-CON18) supplied with kit to the RDGD3100F3PH5EVB and MCU controller board such as the MPC5777C-DEVB. This cable is keyed and is compatible with interface port on MPC5777C-DEVB.
