PFC controller

11 October 2017 Power Electronics / Power Management

Power Integrations’ HiperPFS-4 devices incorporate a continuous conduction mode (CCM) boost PFC controller, gate driver and 600 V power MOSFET in a single low-profile (ground pin connected) power package. They eliminate the need for external current sense resistors, also eliminating their associated power loss, and instead use an innovative control technique that adjusts the switching frequency over output load, input line voltage and input line cycle. HiperPFS-4 uses advanced digital techniques for line monitoring, line feed-forward scaling and power factor enhancement; while using analog techniques for the core controller, in order to maintain extremely low no-load power consumption.
