Abstract

This paper proposes a hybrid control scheme peak current, applied to a single-phase micro inverter with flyback topology coupled to a LC filter, the proposed scheme allows the inverter to operate by boundary conduction mode when the output current exceeds a predetermined value. Otherwise, it operates in the discontinuous conduction mode, limiting the switching frequency. To set the control system in both modes of operation, the inverter is identified by averaging the model state and small signal, the control scheme used, presents a classic PI control and is tuned by pole placement. The proposed control scheme is verified through computer simulation.
