| Abstract: | A novel active power factor corrector is introduced,which is based on active switching or DC/DC converter,i.e. Boost APFC(Active Power Factor Corrector)circuit.The main circuits are given.The operating principle of CCM circuit controlled by the average current and the correction procedure are analyzed in detail.The simulative optimization is done with PSPICE software and the waveforms of inductance currents at relative points are showed.The test is carried out on the 450 W prototype equipment.The PF value of the circuit with APFC increases to above 0.98 from 0.67 of the normal PF circuits.The experiment results and PSPICE simulation both verify the correctness of analysis and design. |
