大容量开关电源的设计

大容量开关电源是蓄电池直流电源系统的重要部件,本文的基本思想是以提高大容量开关电源的总体性能为目的而进行了综合设计.为此,本文介绍了大容量开关电源,分析了电源的动态结构、三相单开关PFC原理及多模块均流,这样,使大容量开关电源有了良好的动静态性能,通过实验、测试证实了这一点,为其他大功率电源开发提供依据.

Design of Switching Power Supply for Large Capacity

Switching power supplies are important parts of DC power supply system of storage battery.the basic idea in the paper puts up integrate design in order to raise collectivity performance for switching largepower supplies.This paper introduces the basic principle of switching largepower supply. The dynamic structure of power supply,the principle of singleswitch threephase PFC and automatic current sharing of modules are also analyzed. By designs favorable performances are achieved which are also approved by some experiments and tests. This paper can provide gist of exploitation for other largepower supplies.
