摘要：The paper proposes a novel single-phase ac-ac converter topology based on Z-source concept. It could provide buck-boost function and make the role of frequency changer. Compared to the traditional ac-dc-ac converter, it uses less devices and realizes direct ac-ac power conversion, has simple circuit structure, so as to have higher efficiency and better circuit characteristics. Compared to the traditional matrix converter, it provides wider voltage regulation range. The circuit topology, operating principle, control method and simulation results are given in this paper, and the rationality and feasibility is verified.
