The zero-voltage switching (ZVS) T-type dc–dc converter has been proposed as an alternative to the conventional ZVS pulsewidth modulated (PWM) full-bridge (FB) converter. Although it has a number of advantageous features, the ZVS T-type dc–dc converter is not well known among power electronic engineers, and the topology has thus been neglected. In this article, the operation of the dc–dc ZVS T-type converter is reviewed and contrasted to that of the conventional ZVS-PWM-FB dc–dc converter. Results obtained from prototypes of each converter topology are then presented, compared, and discussed, and conclusions about which converter is superior for particular applications are made.

用于开关电源的 T 型和 ZVS-PWM 全桥转换器的研究

零电压开关 (ZVS) T 型 dc-dc 转换器已被提议作为传统 ZVS 脉宽调制 (PWM) 全桥 (FB) 转换器的替代方案。尽管它具有许多优点，但 ZVS T 型 DC-DC 转换器在电力电子工程师中并不为人所知，因此其拓扑结构被忽略了。在本文中，对 dc-dc ZVS T 型转换器的操作进行了回顾，并与传统的 ZVS-PWM-FB dc-dc 转换器的操作进行了对比。然后呈现、比较和讨论从每个转换器拓扑的原型获得的结果，并得出关于哪种转换器更适合特定应用的结论。
