摘要
随着分布式电源系统的发展,开关电源并联技术的重要性日益增加。文中介绍了一种新型高频开关电源及220V/10A整流模块的实现方案。其中整流模块采用高可靠性电流型PWM整流器及全桥变换电路来分别实现三相功率因数校正和DC/DC变换,并在模块间采用最大电流自动均流法实现自主均流。
With the development of the distributed power system,the current-sharing method of switch power supply is becoming more and more important.This paper presents a newhigh frequency(HF)switch power supˉply and implementation of220V/10A rectifier modular.The rectifier module implements the3-phase power factor correction and DC/DC conversion usinghighly reliable main circuittopology,and implements the automatˉic current-sharing control using the maximum-current control method.
