摘要
有源功率因数校正电路使输入电流波形跟踪输入正弦交流电压波形,得到较高的功率因数.主要针对APFC控制方法进行讨论,介绍了UC3854控制电路,并设计了功率电路,通过实验证明了此校正电路的优良性能.
Active power factor correction circuit makes input current waveform track the input sinusoidal alternating voltage waveform to get a higher power factor.Control method smainly aimed at APFC are discussed,UC3854 control circuit is introduced,and the design of power circuit is completed.The experimental results show the good performance of the correct circuit.
