Abstract: In order to find the best solution to reduce costs and improve efficiency and reliability of mi-cro-inverter, topologies of micro-inverter in photovoltaic power generation system are reviewed in this paper. Firstly, the advantages of grid-connected micro-inverter and its design objectives are introduced. Combined with the research status at home and abroad, this paper analyzed the typical single-stage and multi-stage micro-inverter topologies, and their advantages and disadvantages are discussed. Aiming at problems existing in micro-inverter, power decoupling technique, elimination of leakage current, and application of novel power devices were studied in order to achieve the goal of low cost, high efficiency, and long life. Through the summary and induction of all kinds of inverter topology, the research direction and future prospects of development are expected in this paper.
