很好，PFC就是“功率因数”的意思，主要用来表征电子产品对电能的利用效率。功率因数越高，说明电能的利用效率越高。
无源PFC怎样计算才是最合适的呢

这书写的太麻繁了
pfc就是线圈 几个元件

是那么简单吗？可见你知道的太少。

请问无用功部份能量以什么形式释放了？因为能量总是要守恒的。 电路 电子 维修 我现在把定影部分拆出来了。想换下滚，因为卡纸。但是我发现灯管挡住了。拆不了。不会拆。论坛里的高手拆解过吗？ 评论 认真看，认真瞧。果然有收 电路 电子 维修 求创维42c08RD电路图 评论 电视的图纸很少见 评论 电视的图纸很少见 评论 创维的图纸你要说 版号，不然无能为力 评论 板号5800-p42ALM-0050 168P-P42CLM-01
