TMS320F28035: interleaved PFC current balancing

Part Number: TMS320F28035
Other Parts Discussed in Thread: CONTROLSUITE

Hi,

we have reference design of ILPFC in ControlSUITE.

But we don't provide current balancing software.

Now the customer doesn't sense the total current, they only sense the two MOSFETs' current.

Do we have reference code for interleaved PFC with current balancing?

    For the interleaved PFC design inductor current in each phase is pretty balanced by itself. So we did not implement this balancing control loop and we don't have any code to share at this time.

    If the customer needs this then they have to write their own code. They can compare the sensed MOSFET currents and use the current error (i.e. current imbalance) to correct the PWM duty.
