摘要
提出一种适用于多路输出应用场合的新型电流型移相控制全桥PWM DC-DC变换器,它能够利用辅助电路和寄生参数分别实现上下四个主开关管的零电压和零电流工作。且辅助开关管也可以零开关工作。本文分析了它的工作原理以及实现软开关的条件,最后在Pspice中验证理论的正确性和可行性。
The proposed novel current-fed phase-shift full-bridge PWM DC-DC converter is applicable to multioutput applications. This converter uses auxiliary circuits and parasitic parameters to achieve ZVS and ZCS. And the auxiliary switches can work softly too. This paper analyses its operational principle and the condition of achieving soft-switch, and finally verify the correctness and feasibility of the theory in Pspice.
