By comparing the different generator's magnetic circuit and mathematical model, a permanent flux-switching generator was applied to the open winding generator system. The other focus of this paper was the generation and suppression of the system's inherent output voltage ripple. This paper established a small signal model of the system, then drew the impedance's specific analytical expressions based on the averaged switching model. This paper used Middlebrook criterion to analyze the source and load impedances' matching, the ability of ripple suppression under different system parameters. Then a fast system parameter design method was proposed. The experiments were carried out on a flux-switching generator system. The results illustrate the validity and effectiveness of the proposed method.
