在网上看到的一篇文章，觉得还不错，分先给大家

老式TL494_KA7500半桥ATX电源三极管改进为NMOS (发起人：ShadowFerry)

ImproveOld Half-bridge ATX Power Supplies from BJT to NMOS(Initiator: Shadow Ferry)

前言：

F.1:生命没有彩排！！！务必确保所有变压器即使在单一介质/热失效时也至少满足加强绝缘！！！F.2:莫要机械模仿！你可能需要按实际情况调节参数。该文也可能存在错误。

F.3:作为业余爱好者，意在用相似部件微调架构减轻我们共同的地球母亲的资源和能源消耗。

F.4:已经大致比较出修改后次级使用TMBS®或SBR®二极管的NMOS半桥达80 PLUS®银牌等级。

Forewords:F.1: LIFE IS NOT A REHEARSAL!!! Do make sure that all thetransformers are reinforced insulated at least even if there is a single dielectric/thermal failure!!!F.2: DONOT BE A COPYCAT! You may have to adjust the parameters according to your real situation,and also there might be errors in this article.F.3: Asan amateur, the initiator intends to relive the earth, our co-mother, ofresource & energy consumption while we are using similar components but tinydifferent architecture.F.4: Itis roughly compared that the modified NMOS half bridge with secondary TMBS® (TrenchMOS Barrier Schottky) or SBR® (Super Barrier Rectifier) diodes reaches the 80 PLUS®silver rank.
