In order to solve the problem of the secondary power disturbance in grid-connected photovoltaic system, a power decoupling circuit with three-port is proposed based on a flyback micro-inverter. One of the ports can be used to replace the short lifetime capacitor with long lifetime film capacitor to achieve power decoupling and improve the overall life of the inverter. Simulation and experiment verify the feasibility and stability of the decoupling circuit.
