A Question for Document "“HVMotorCtrl + PFC” Kit How to Run Guide" (28035)

Hello Everyone,

I use 110VAC 1 phase power to High Voltage Motor Control and PFC Kit (TMDSHVMTRPFCKIT 28035). I find it only runs properly at a certain speed. When I read "“HVMotorCtrl + PFC” Kit How to Run Guide" on Page 4, I find this small font message as below:

* Note that the 3-ph Induction motors are typically rated at 220V AC, so the 320 V DC-bus voltage is needed. Thus when using

110V AC power source to generate the DC Bus for the inverter the motor can run properly only at a certain speed and torque

range without saturating the PID regulators in the control loop. As an option, the user can run the PFC on HV DMC drive

platform as boost converter to increase the DC bus voltage level or directly connect a DC power supply.

In last sentence, It says "the user can run the PFC on HV DMC drive platform as boost converter to increase the DC bus voltage level". I have a question to ask you. If I want to get "boost converter" function from PFC, do I only connect PFC in hardware; Or I need connect hardware, then program software as driver for PFC and load it to MCU?

Regards,

Hao

  • Yes Hao,

    You would need to program  for the PFC stage to work, The PFC stage present on the board is an active two phase interleaved stage with PWM control mapped to the control card,

    We currently do not have a released PFC software for this kit,
