Any suggestions on topologies for three phase PFC circuits suitable for control by eg the UCD3138? Is a three phase extension to the bridgeless converter design used in the UCD3138PFCEVM-026 feasible?
In the design I'm considering, the DC output from the PFC stage is used as the input to a ZVS H-bridge, thus my other post re availability of an evaluation board for a PSFB design. Not many answers coming back on that :-(
