摘要：本文介绍了移相控制全桥型零电压变换电路的工作原理，该电路将移相控制技术和全桥变换电路结合在一起，有效地减少了开关损耗，提高了工作效率，并且不会发生开关应力过大的问题，同时介绍了UC3875的应用。
叙词：移相控制；全桥；零电压开关；脉宽调制；超前桥臂；滞后 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.
