| 摘 要： | 针对常规推挽变换器中变压器的漏感会在开关管两端产生电压尖峰的问题，有源钳位推挽变换器可以有效地对此现象进行抑制。本文对推挽变换器的数学模型进行分析，使用二阶工程设计法整定有源钳位推挽变换器中的电压负反馈PI调节的参数值，并且通过仿真与实验的验证，确保有源钳位推挽变换器可以稳定高效地运行，同时消除了由变压器漏感引起的开关管两端电压尖峰。

| Abstract: | As the leakage inductance of the transformer will place an overvoltage at the switching devices in conventional push-pull converter ,the active clamped push-pull converter can greatly suppress this phenomenon .This paper analysis the mathematics model of push-pull converter ,adjust a proper value of the PI voltage feedback in the active clamped push-pull converter with second order engineering design method , and ensue this converter can work stably and efficiently with a suppression to the overvoltage at switching devices confirmed by simulation and experiment . |
