多谢
像那些耐高压的电容,大功率电阻,还有两个芯片价格都不算高吗?
如果用正品大概多少钱 呢?
那个IR21592和MC34262或者L6560大概多少钱呢?

用220V AC还是110V AC供电?
如果是220V AC,用IRF830作PFC BOOST的耐压够吗?

是220VAC,为什么不能用IRF830,我看IRF830的数据表上耐压为500V啊
APFC输出为400V,不行吗?

用到耐压的80%,比较悬.如果启动的时候控制环路有过冲,或者遇上市电波动,可能就会击穿.

840的datasheet说耐压有温度系数(大概是每度一伏),没注意是正温度系数还是负温度系数.如果是负的,就肯定不能用.

《电子工程师》上有一篇前面用TOP224做PFC,后面用自振半桥的文章,他的APFC输出是400V,MOSFET用的是1117.

当然够用了,主要是升压电、感要设计好.
