Abstract

A novel ZCS PWM converter with dual converter operation is proposed. All switches in the proposed converter are operating to work alternatively turn-on and turn-off with soft switching condition. The switch S2 in the conventional ZVT converter plays a part as the auxiliary switch to operate the main switch S1 and the rectifier in the soft switching condition during the transition period. But the switch S2 in the proposed converter has two roles as both the auxiliary switch to hold the soft switching condition and the main switch for a dual operation. A 100 kHz, 200 W boost converter has been implemented to verify the operation and performance of the proposed converter.

新型ZCS PWM变换器,操作双变换器
提出了一种新型的双变换器ZCS PWM变换器。所提出的变换器中的所有开关都在软开关条件下交替工作。传统ZVT变流器中的开关S2在过渡时期软开关状态下起辅助开关的作用,对主开关S1和整流器进行操作。但该变换器中的开关S2有两个作用,既是保持软开关条件的辅助开关,又是双重工作的主开关。一个100khz, 200w的升压变换器已经实现,以验证所提出的变换器的工作和性能。
