Other Parts Discussed in Thread: UCC28070A

I am looking for an interleaved boost PFC controller to supply 8KW, What controller would be a good choice?

Input AC: 480-575 VAC single phase

Output DC 800Vdc at 100A

    The UCC28070A is an interleaved CCM type pfc controller and you should consider using it in such an application. The resistors sensing the input AC and the DC output can be scaled for the high voltages in your design. The UCC28070A ha a lower frequency limit of 10kHz which makes it suitable for driving IGBT's
