PROGRAMMABLE FREQUENCY – CONTINUOUS CONDUCTION MODE (CCM) – BOOST POWER – FACTOR CORRECTION (PFC) CONTROLLER
The circuit described here is a simple PFC controller using the UCC28180 chip from Texas instruments. The controller operates under average current mode control at a fixed programmable switching frequency of 116 kHz. Simple external current and voltage loop compensation, along with advanced protection features, make this controller ideal for server and desktop power supplies, industrial power supplies, and white …
