Abstract

Among the different PFC topologies, totem-pole PFC is attracting more attention because it can offer the highest efficiency among the bridgeless PFC topologies. Due to more complicated schemes and special requirements to support boundary conditions, it is common to use digital controller for the totem pole PFC. This application note discusses several control schemes to optimize the totem pole PFC performance based on C2000 real-time MCU, in order to achieve more reliable and flexible system designs.
