A Simple Implementation of the Totem-Pole Boost PFC Circuit

For Power-Factor-Correction(PFC) circuit,it's a more important aspect to get higher efficiency.Totem-Pole Boost with no rectifier bridge can get better performance in theory.In this paper,after theoretical analysis for Totem-Pole Boost PFC circuit,a simple way to realize this circuit with traditional Boost PFC control IC is proposed.Simulative and experimental results verified its feasibility.Based on experimental results,point out the disadvantage of the topology and indicate its potential.
