In this paper, the interleaved flyback inverter is proposed since the topology has been widely used for PV grid-tied micro-inverter applications. The micro-inverter configuration allows to control each photovoltaic (PV) module independently and reduce the mismatch loss, which is common in string and utility inverters. Flyback inverter traditionally operates in discontinuous conduction mode (DCM) or boundary conduction mode (BCM) due to its simplicity in controller design. In this study, the controller has been designed for continuous conduction mode (CCM) operation in order to reduce component stress and increase power density. The current control is based on the primary side, which is an indirect regulation for the grid outflow. A small signal model is also developed for the controller synthesis. Simulation verifies the performance of the proposed inverter.
