采用新型无源缓冲电路的单相功率因数校正器

Single-phase power factor corrector with a novel passive snubber circuit

介绍了单相功率因数校正器的工作原理及控制电路的参数选择。由于采用了一种新型的低损耗无源缓冲电路 ,开关管和主二极管的电流电压应力较小 ,并降低了能量损耗 。

The principle of single phase power factor corrector and the parameter selection of the control circuit are demonstrated.Since the novel low-loss passive snubber circuit is used,the low current and voltage stress,low energy loss and high efficiency properties are achieved.
