摘要
本文简单介绍了一种加箝位二极管的移相全桥零电压直流变换器的工作原理,详细分析了箝位二极管的工作过程。在仿真和理论分析的基础上,对箝位二极管的参数计算方法进行了研究,通过研制5kW移相全桥软开关DC/DC变换器,验证了箝位二极管计算方法的正确性。该电源已应用在某重点项目中。
In this DC converter wit paper, h clam analysis, A prototype of the operating principle of a phase shifted full-bridge zero-voltage -switching （PSFB ZVS） DC/ ping 5kW diodes is introduced. The effects of the clamping diodes are detailed. Based on the above PSFB ZVS DC/DC converter is fulfilled. The experimental results and simulation confirm that the computer of clamping diodes is very suitable for this converter. It is applied in a large item successfully
