摘要

本文主要研究并联DC-DC变换器的电流分担问题，以期为采用公共直流母线的DC-DC变换器提供均衡负载。考虑级联控制系统结构，首先设计内部多变量电流比例控制器，然后构建外部电压积分控制器，以保持直流母线的期望输出电压。给出了采用脉宽调制器并联直流变换器的系统仿真结果。

Current-sharing and DC bus voltage control system design of paralleled DC-DC converters

The paper is dedicated to problem of current sharing of paralleled DC-DC converters in order to provide balanced loading of DC-DC converters with common DC bus. Cascaded control system structure is considered where, at first, an inner multivariable current proportional controller is designed and then, at second, an outer voltage integral controller is constructed in order to keep the desired output voltage of the DC bus. Simulation results of the system with the three paralleled DC converters equipped by the pulse-width modulators are presented.
