Description

Totem Pole PFC and CLLLC resonant converters are a popular choice of power converter topology for on-board charging (OBC), charging station, even server and telecom applications.

This design illustrates Constant Conduction Mode (CCM) Totem-pole PFC control as well as frequency and phase modulation control of the CLLLC resonant converter on a single C2000™ real-time MCU. The design is compatible with both TMS320F28P650DK or TMS320F280039C MCU.
