© 2019 The Korean Institute of Power Electronics (KIPE). In this paper a new single-phase flying-inductor buck-boost inverter is proposed. The inverter operates on the principle of flying-inductor, and it has the capability to buck or boost the input voltage without increasing the number of required components. In addition, the inverter is free from electrolytic capacitors, which helps to improve reliability and lifetime of the inverter. The operating principle of the proposed inverter has been analyzed and discussed. Finally, experimental results from a 250 W prototype validates the performance of the proposed topology.
