建議你用半橋做吧,很容易稿定的,

單端正激電路也不錯哦!后級雖然也需要兩個管子,但控制簡單,也比較容易穩定.推薦!!

是單端雙管正激吧!EC40的變壓器 夠嗎??能否建議全點?您做過嗎??半橋容易磁偏!我不打算用!

還有 同步整流 你用什么片子  有興趣加我QQ  我們聊聊!!大家哪位正在做,也想做的,已經做過的  有興趣就加我 聊聊!!!!

電壓模式半橋是抗磁通不平衡最強的拓撲,根本不會發生偏磁
因為輸入變壓器的電路有電容隔直,變壓器上不可能出現直流分量

不錯

用雙管正激和半橋都是比較好的選擇,也可以考慮全橋,和交錯式雙管正激.PFC用CCM模式的.

電源不怕短路  就是;厲害!!!短路電壓0.19V

很對!

不錯的東東

沒下文了?

做出了嗎?
