摘　　要：该文提出了一种功率变换的模糊型跨周调制模式(Fuzzy Pulse Skip Modulation,FPSM),它是基于作者提出的功率变换跨周调制(Pulse Skip Modulation,PSM)机理的一种优化模式。PSM是功率变换的一种新调制模式,它具有效率高、响应速度快、鲁棒性强等特点。该文给出了FPSM输入输出变量的隶属函数、模糊控制规则和解析结果。分析表明FPSM除具PSM之优点外;同时较PSM有效降低了变换器的输出电压纹波,消除了音频噪音影响。A novel modulation mode named Fuzzy Pulse Skip Modulation(FPSM) in power converter is proposed in this paper, which is based on Pulse Skip Modulation(PSM) mode proposed by authors recently. PSM is a novel modulation mode in power converter, which has high efficiency, quick response and strong robust qualities. This paper gives the membership function, fuzzy rule and analysis results of FPSM. It is shown that FPSM not only has high efficiency, quick response and strong robust characteristics, but also decreases the ripple of output voltage and eliminates audible noise through analysis and simulation.
