摘    要:为了克服硬开关电源尖峰干扰大、可靠性差、效率低的缺点,分析了全桥移相软开关电路超前臂和滞后臂的不同工作状态,讨论了全桥移相软开关电路的占空比丢失现象,对软开关谐振器超前臂、滞后臂的并联电容和串联电感参数进行选取.通过试制4 kW全桥移相ZVS软开关电源,获得了变压器前端电压和电流波形.结果表明:开关管实现了零电压变换,验证了谐振电感和谐振电容参数选取的正确性.

关 键 词:全桥移相  软开关  谐振

Abstract:Directed at overcoming the hard-switching power supply's shortcomings,such as great peak interference,poor reliability,and low efficiency,this paper analyses the different states about the leading arm and the lagging arm of the full-bridge phase-shifting soft-switching circuit and discusses the duty factor loss of full-bridge phase-shifting soft-switching circuit.The paper also gives the choice of the parameter of the parallel capacitance and series inductance in the soft-switching resonator's leading arm a...
Keywords:full-bridge phase-shifting  soft-switching  resonance
