本文对PWM全桥软开关直流变换器进行了研究。具体阐述了PWM全桥ZS软开关直流变换器的工作原理和软开关的实现条件，就基本的移相控制FB ZVS PWM变换器存在的问题给予分析并对两种改进方案进行了研究：1、能在全部工作范围内实现零电压开关的改进型全桥移相zvs-PWM DCDC变换器，文中通过对其开关过程的分析，得出实现全负载范围内零电压开关的条件。采用改进方案设计了一台48V~6 VDC/DC变换器，实验结果证明其比基本的 ZVS-PWM变换器具有更好的软开关性能。2、采用辅助网络的全桥移相 ZVZCS-PWM DCDC变换器，文中具体分析了其工作原理及变换器特性，并进行实验研究随着电力电子技术的发展，功率变换器在开关电源、不间断电源、CPU电源照明、电机驱动控制、感应加热、电网的无功补偿和谐波治理等众多领域得到日益广泛的应用，电力电子技术高频化的发展趋势使功率变换器的重量大大减轻体积大大减小，提高了产品的性能价格比，但采用传统的硬开关技术，开关损耗将随着开关频率的提高而成正比地增加，限制了开关的高频化提高功率开关器件本身的开关性能，可以减少开关损耗，另一方面，从变换器结构和控制上改善功率开关器件的开关性能，可以减少开关损耗。如缓冲技术、无损缓冲技术、软开关技术等软开关技术在减少功率开关器件的开关损耗方面效果比较好，理论上可使开关损耗减少为零。12软开关技术的原理和类型功率变换器通常采用PwM技术来实现能量的转换。硬开关技术在每次开关通断期间功率器件突然通断全部的负载电流，或者功率器件两端电压在开通时通过开关释放能量，这种方式的工作状况下必将造成比较大的开关损耗和开关应力，使开关频率不能做得很高。软开关技术是利用感性和容性元件的谐振原理，在导通前使功率开关器件两端的电压降为零，而关断时先使功率开关器件中电流下降到零，实现功率开关器件的零损耗开通和关断，并且减少开关应力。
