360-W PFC to full-bridge battery charger reference design This reference design is comprised of a PFC boost: hard-switched full-bridge and bias flyback to make a universal AC-input battery charger. The charging current is configurable with a maximum value of 6 A. The output voltage can vary from 18-V to 63-V maximum charge and is also configurable. The PFC stage utilizes the UCC28180 CCM PFC controller to maximize efficiency. The UCC2808A push-pull controller and two UCC27710 half-bridge drivers create the full-bridge power stage. The bias flyback uses the UCC28911 integrated MOSFET flyback converter.
