随着装备信息化的发展，各种仪器设备对电源容量的要求越来越高，而多模块并联是增加直流电源容量的主要途径之一。针对并联系统中由于单体特性不同造成的负载电流不平衡问题，分析了几种常用均流方法的优缺点，并采用最大电流均流法设计了均流控制策略，在电压电流双闭环控制基础上增加了一个均流环，形成一个三环控制系统。利用Matlab搭建了2个电源模块并联仿真模型，分别进行了有均流环和无均流环2种情况下的仿真，并进行了实验验证。实验结果表明该均流控制策略具有较好的均流效果。

With the improvement of equipment information level, all kinds of instruments and equipment have a higher and higher demand for the DC power capacity. While, multiple modules in parallel are the main way to increase the DC power capacity. In this paper, the load current imbalance for parallel system due to the different characteristics of monomer was investigated, and the merit and demerit of each method of current-sharing were analyzed. Then the cur-rent-sharing control strategy was designed based on peak-value current-sharing method, which added a current-sha-ring to the original double-loop, forming a three-loop control system. A simulation model of two power modules in par-allel was built using Matlab, then simulation and experimental verification in the case with current sharing loop and that without current sharing loop were carried out. Experimental results show that the current-sharing control strategy has good flow effect.
