| 摘 要： | 提出了一种ZVS双正激直/直变换器拓扑，该拓扑不仅保留了双管正激变换器开关电压应力低、可靠性高的优点，而且较普通的交错并联双管正激变换器减少了两个箝位二极管。电路不仅实现了原边开关管的零电压开通和关断，而且副边整流二极管不存在电压尖峰。文章详细分析了该变换器的工作原理，给出了变换器的输出特性和实现ZVS开通的条件，并用一个2kW的原理样机进行了验证，最后给出实验结果。

| Abstract: | An interleaved two-transistor forward converter with th e zero voltage switching (ZVS) is presented. This converter retains the advantag es of two-transistor forward converter, such as low switch voltage stress, high reliability, and has only two camping diodes in comparison with the convention al interleaved two-transistor forward converter. Moreover the converter achieve s ZVS of the active switches and eliminates the voltage overshoot of the output rectifying diodes. The operational principle, the output characteristics and the condition of ZVS turn-on of the switches are illustrated. And the effectivenes s of the given converter topology is verified by a 2 kW prototype. Finally, expe rimental results are given. |
