1.3.2 The High-Voltage Power Domain

This domain represents the DC-link section powering the inverter that generates three-phase voltages for the motor.

The following are ways to provide this voltage to the inverter:

  • Connect an external isolated variable DC-power supply (maximum 350 V) using banana jacks to [Main]-BS2 and [Main]-BS3 of IDDK. TI recommends using this power supply during experiments. To power the auxiliary power supply modules [M2]/[M8], connect [Main]-BS3 and [Main]-BS1.
  • Connect the kit to AC Mains through P1 (110 V or 220 V AC). An onboard rectifier converts AC to DC. For your safety, TI recommends using a variable AC transformer (variac) and isolator when using this power source.

NOTE

Keep power supplies at zero unless directed to energize.

The 3-phase induction motors are typically rated at 220-V AC. You need a 320-V DC-bus voltage. When using 110-V AC-power source to generate the DC bus for the inverter (150 V), the motor can run properly to a certain speed and torque range without saturating the PID regulators in the control loop. You can connect directly to a DC-power supply.

WARNING

The ground planes of both the power domains can be same or different depending on hardware configuration.

Meet proper isolation requirements before connecting any test equipment with the board to ensure the safety of yourself and your equipment.

Review the GND connections in the DesignDRIVE IDDK Hardware Reference Guide before powering the board.
