| 摘 要： | 提出了一种自激式零电压ＤＣ－ＤＣ变换器，分析了工作原理及实现全范围软开关的参数设计，该变换器不同于依靠变压器磁化曲线形成状态转换的传统方式，工作频率由外部器件控制，通过设置死区时间实现开关功率器件的零电压开通与关断，利用该变换器研制出ＧＴＯ门极驱动用电源。

| Abstract: | A new self-excited zero-voltage-switchi- ng(ZVS) DC-DC converter is proposed. The operation principle and parameter design of accomplishing soft-switched in a full range is analyzed.The converter rejects conventional state transition mode based on the magnetized curves of a transformer. The operation frequency is decided by the side parts. The turn-on and turn-off of power devices under zero voltage are realized with addition of dead time. The power supply for GTO gate driver is developed by use of the converter. |
