摘要
为强化DC/DC变换技术的实践教学,基于多绕组变压器和反激电路原理,本文开发一套DC/DC变换器教学系统。设计变换器的拓扑结构,分析工作原理及控制策略,计算变换器系统参数,建立数字仿真模型,设计变换器主电路、输出电压采样电路、开关管驱动电路等来搭建变换器实验平台。实验教学应用表明,该变换器实现宽输入/输出电压范围功能的同时,能够提高学生的电力电子技术综合实践能力。
In order to strengthen the practical teaching of DC/DC converter technology,an experimental system of DC/DC converter is developed based on multi-winding transformer and flyback circuit principle in this paper.The topology structure of the converter is designed,its working principle and control strategy are analyzed,the system parameters of the converter are calculated and the digital simulation model is established.The main circuit of the converter,the output voltage sampling circuit and the switch driver circuit are designed to build the experimental platform of the converter.The application of experiment teaching shows that the converter can realize the function of wide input/output voltage range.It can also improve students'comprehensive practical ability of power electronics technology.
