摘要
现在的配网自动化系统中使用最广泛的是开关电源,这是由于它具有小体积以及高效率的优点。双管正激拓扑结构由于磁复位简单、开关电压应力低、无桥臂直通短路的危险,因此具有广阔的应用前景。文中介绍了一种大功率开关电源的典型原理设计,针对双管正激拓扑结构的要点进行了原理分析和公式推导,总结出开关电源关键器件的选型要求。
Switching power supply has the advantages of small size, high efficiency, which is widely used in distribution automation system. Due to the simple magnetic reset, low switching voltage stress and no risk of bridge arm short - circuiting, the dual - transistor forward topology has broad application prospects. In this paper, a typical principle design of high power switching power supply is introduced. The principle analysis and formula derivation are given for the main points of double forward topology, and the selection of the key components of switching power supply is concluded.
