Zero-Voltage Switching Push-pull Forward DC/DC Transformer

提出了一种零电压开关推挽正激直流变压器(Zero Voltage Switching Push-pull Forward DC/DCTransformer,简称ZVSPPFDC/DCT)。它利用漏感实现了功率管的零电压开关,可广泛用于不间断电源、电压调整模块、分布式系统、航空静止变流器、功率因数校正、多路输出等领域。文中详述了该电路的工作原理,分析了实现零电压开关的条件,并进行了仿真分析。最后,在1kW零电压开关推挽正激直流变压器的原理样机上验证了理论分析的正确性。

A zero-voltage-switching （ZVS） push-pull forward DC/DC transformer is illustrated in this paper.The switches can realize ZVS with leakage inductors.h can be widely used in UPS,VRM,DG,aeronautical static inverter,PFC and multiple output configurations etc.The operational principle, the condition of realizing ZVS and simulation analysis are introduced in the paper.Finally,experimental results of a 1kW ZVS push-pull forward DC/DC transformer are given to verify theoretic analysis.
