| 摘 要： | 为了减少电力电子装置引起的谐波污染,加入APFC控制策略是一种有效的方法。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。文章主要针对APFC控制方法进行讨论,介绍了NCP1654控制电路,并设计了600 W功率电路,实验结果证明了此校正电路的优良性能。

| Abstract: | 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 factor 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. |
