Design of High Power Factor Flyback Switching Power Supply Transformer

WU Lizhen

Abstract

Transformer design of switching power supply is complex and critical.The transformer principles of the flyback switching power supply with high power factor(PF) is discussed.Based on this,a new good design method is introduced and the results are proved by experiment.The transformer has high transmission efficiency,low EMI,low leakage,low tempera-ture rise.
