1.3.1 The Low-Voltage Power Domain

This domain represents the 15 V, 5 V, and 3.3 V to power the MCU, logic, sensing, and driver circuits on the IDDK.

The power input for this domain can be provided using the following methods:

  • Connecting an isolated 15-V DC-power supply to the DC-jack ([M3]–JP1/[M9]–JP1) on the DC-power entry macro.
  • Using an auxiliary power supply module ([M2]/M[8]) on the board that can generate 15 V and 5 V DC from the high-voltage DC link.

    • NOTE

    Because the input voltage range of this module is from 90 V to 400 V, the auxiliary modules are unsuitable if the DC-bus voltage goes below 90 V during the tests. In such cases, TI recommends using the first method.
  • Configuring [M3] and [M9], which are identical macros that provide the same set of output voltages, to power the entire controller or the gate drives of the inverter. For more information, see the DesignDRIVE IDDK Hardware Reference Guide.

For the default configuration of the kit:

  • Set up [M9] as the low-voltage power source.
  • Both control GND and power GND planes are separated into COLD and HOT GNDs, respectively. In the previous release of IDDK [R2.2], they were tied together making them all HOT.
  • Do not use shunt current and voltage sensing.

For applications requiring a HOT control GND:

NOTE

The control GND and power GND can be separate or tied together. If control GND and power GND are tied together, the control GND is HOT. If they are not tied together, the control GND is COLD and will need a separate control power supply for the HOT and COLD sides.

For your safety and convenience during general code development, testing, and verification, use an external isolated 15-V power supply to power the control section of the board through DC-power entry macro [M9].
