It is an effective method that active power factor correction (APFC) is added into the power electronic deceives to reduce the harmonic pollution caused by these deceives. Active power faetor correction circuit makes input current waveform track the input sinusoidal AC voltage waveform to get a higher power factor. Control method mainly aimed at APFC are discussed in the paper, NCP1654 control circuit is introduced, and the design of a 600 W power circuit is completed. The experimental results show the good performance of the correct circuit.
