主从控制ISOP反激变换电路的研究

介绍了一种适用于输入串联输出并联(ISOP)系统中的主从控制策略,分析了该控制策略的实现方式。主模块控制系统的输出电压,从模块实现模块间的输入均压和输出均流。仿真结果表明,在负载突然变化的情况下,输出电压在主模块的控制下总是保持不变,而两个模块的输入电压和输出电流时刻保持一致,说明了从模块的控制电路实现了输入电压和输出电流的均衡,验证了所提方法的正确性。

Research on Input-Series Output-Parallel Fly-Back Converter of Master-Slave Control

Introduction was made to a kind of master-slave control strategy, which is suitable for the input-series and output-parallel (ISOP) system. This paper analyzed the realization method of the control strategy. The master module controlled the output voltage of the whole system, while the slave module balanced input voltage and output current of every separate module. The simulation results show that under the condi-tions of abrupt load change, the output voltage controlled by master module remains unchanged and the input voltage and output current of the two modules stay the same at any moment, which balances the input voltage and output current from the module controlled circuit and verifies the validity of the proposed method.
