摘要:本文介紹了移相控制全橋型零電壓變換電路的工作原理,該電路將移相控制技術(shù)和全橋變換電路結(jié)合在一起,有效地減少了開關(guān)損耗,提高了工作效率,并且不會發(fā)生開關(guān)應(yīng)力過大的問題,同時介紹了UC3875的應(yīng)用。
敘詞:移相控制;全橋;零電壓開關(guān);脈寬調(diào)制;超前橋臂;滯后 Abstract: This paper introduces the operation principle of PSC FB ZVC-PWM convert circuit, PSC technology and Full-bridge convert circuit integrated into one stage. The switching losses can be effectively reduced. The efficiency is improved, and it cant happen switching stress too great. At the same time, this paper introduces the application of UC3875.
