谐振、准谐振或多谐振技术方案，变换器的电压电流应力较高，变频控制增加了滤波器设计的难度；能量缓冲吸收电路或有源钳位电路方案，由于需要增加多个额外辅助元件，增加了变换器的复杂性；全桥相移技术方案，由于主电路无需增加额外元件，只需利用相移控制，即可实现软开关，因此引起关注。 - The soft switching , phase - shifted pwm and bi - directional dc - dc converter hang together , depress circuit switching loss and noise effectively , which provide condition to increase switch frequency , efficiency and reduce size and weight for the converter ; at the same time , it is proved the converter can achieve zvs in larger load variation , and the converter has the virtue of structure compact , voltage and current stress small such as ordinary hard switch converter
