Part Number: TIDM-02002

I have a project would be use C2000 to implement the 10kW Bidirectional AC/DC converter for Automotive application, but I have one question what would be the auxiliary power in the bidirectional converter?  if I need to do the auxiliary power in the converter, there are 4 high voltage input flyback should be available in the converter, first is from AC/DC PFC left to right forward power, second is DCDC from left to right forward power, on the other hand form right to left reverse power also have two for DCDC and PFC both, right?   for the real application would the 12V be the auxiliary power?  does TI have any demo design for the reference?

  • William, In my opinion for bi-directional power converters the power can be sourced from the HV battery. We currently do not have a bias power supply design for the TIDM-02002 but will work on it in the next few months. I have copied my colleague to advise any further on this topic.
