摘　　要：简述了开关电源并联运行控制基本原理,针对单个并联电源模块给出了一种串联校正控制模型,并讨论了两个并联模块并联运行时的三环控制结构,给出了各主要部分的仿真模型。利用MATLAB对三环控制结构的开关电源模块并行运行系统进行仿真,并对负载扰动情况下的仿真图形和数据进行对比分析。仿真结果表明,利用三环控制结构对模块数的变化具有较好自适应性,模块间相互不受影响,控制结构合理,各模块配流容易设置、输出电流精准、并联输出电压稳定等特点。The basic principle of parallel operation control of the switch power supply was briefly described firstly. Then a kind of series corrective control model was designed according to the single parallel power supply module. Finally the three-loop control structure was discussed when the two parallel modules run, offering the main part of the simulation model. MATLAB was used to simulate the parallel operation system with three-loop control structure in switch power supply module. The load disturbance of the simulation and data were compared and analyzed individually. The simulation results showed that the three-loop control structure had many advantages, such as the good adaptability of three-loop control structure to the number of module, no influence between the two modules, the reasonable control structure and easy assignment of modules, the accurate output current, the stable output voltage, etc.
