Digitally controlled high efficiency and high power density PFC circuits
This three-part series is focused on digitally-controlled, high-efficiency and high-power density PFC circuits in C2000™ microcontrollers.
In recent years, more attention is focused on increasing power conversion efficiency and power density for universal input power factor correction (PFC) converters while maintaining high power factor (PF) and low input current total harmonic distortions (THD). Our C2000™ MCUs with DPWM modules and integrated analog peripherals are uniquely positioned to implement efficient digital control of such power converters. This presentation will introduce two bridgeless PFC designs using C2000 MCU.
