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?
