摘要
Buck变换器并联是工程上常用的增加电源容量的方法,采用在并联Buck变换电路中增加电感从而达到均流的目的。有两种方式,一是电感加在各Buck模块内部,二是电感加在主电路上。本文对并联Buck电路进行了原理分析以及仿真研究,仿真试验验证了两种方法均可不同程度地实现模块均流。
Parallel-connected Buck converter is a technique which is often used to enhance the capacity of the power supply. Accessing inductance to the buck converter circuit can make the current of every branch balanced. There are two ways, that is, one is adding inductance to the inside of the every Buck modules, and the other is adding inductance to the main branch. This paper analyzes the working principle of Parallel-connected Buck converter, whose simulation results prove that the two ways can all equal the current in different degree.
