This paper builds the small - signal model of the ml converter , and decouples the converter into several independent single - input single - output systems with the control strategy proposed in [ 8 ] , so the closed - loops for the output voltage and the flying capacitor voltages can be designed independently 本文首先建立了buck多電平變換器的小信號(hào)模型,并利用文獻(xiàn)[ 8 ]提出的控制方法將該變換器解耦成多個(gè)單輸入單輸出系統(tǒng)。
