摘 要:介紹了一種適用于輸入串聯(lián)輸出并聯(lián)(ISOP) 系統(tǒng)中的主從控制策略,分析了該控制策略的實(shí)現(xiàn)方式。主模塊控制系統(tǒng)的輸出電壓,從模塊實(shí)現(xiàn)模塊間的輸入均壓和輸出均流。仿真結(jié)果表明,在負(fù)載突然變化的情況下,輸出電壓在主模塊的控制下總是保持不變,而兩個(gè)模塊的輸入電壓和輸出電流時(shí)刻保持一致,說明了從模塊的控制電路實(shí)現(xiàn)了輸入電壓和輸出電流的均衡,驗(yàn)證了所提方法的正確性。

Abstract: 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 conditions 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.
Key words: fly-back converter; input-series output-parallel; master-slave control; balance voltages and currents
