| Abstract: | There are much more harmonics and lower power factor in discontinuous conduction mode(DCM) APFC circuit,which doesn't meet the developing requirements of low-cost high-performance in small power switching power supply.Based on analysis of operating principle and harmonic spectrum,a kind of harmonic compensation circuit is designed to solve above problems.Simulative design of compensation circuit is carried out with Saber software,experiments are also made.The experimental results verify the correctness of t... |
