摘要： A power factor correction (PFC) circuit includes an inductor, a diode, a storage capacitor, a switch and a control unit. The input power has a voltage fluctuation V1. The storage component absorbs a first voltage fluctuation and a switch regulation circuit absorbs a second voltage fluctuation V2. Thus output voltage from the PFC circuit is not a conventional constant voltage but a voltage of a great ripple. The PFC circuit further has a harmonic regulation unit. The harmonic regulation unit generates a voltage signal containing 3rd harmonic. The control unit receives a feedback signal and the voltage signal containing 3rd harmonic to generate a reference to the inductor current. Therefore, the inductor current contains 3rd harmonic. Thus power fluctuation absorbed and released by the capacitor is smaller. As a result energy storage capacitance can be reduced significantly.
摘要翻译：功率因数校正（PFC）电路包括电感器，二极管，存储电容器，开关和控制单元。输入功率具有电压波动V1。存储部件吸收第一电压波动，开关调节电路吸收第二电压波动V2。因此，来自PFC电路的输出电压不是常规的恒定电压，而是具有很大纹波的电压。 PFC电路还具有谐波调节单元。谐波调节单元产生包含三次谐波的电压信号。控制单元接收反馈信号和包含三次谐波的电压信号以产生对电感器电流的参考。因此，电感电流包含三次谐波。因此，由电容器吸收和释放的功率波动较小。因此能够显着降低储能电容。
