摘要：

This paper proposes an optimal control strategy for the interleaved flyback based micro-inverter to improve its efficiency over the entire operating range. This control scheme is based on the choice of appropriate operating mode (among 1-phase DCM; 1-phase BCM; 2 phase DCM and 2-phase BCM) at various instantaneous power magnitudes. Operating mode selection of the interleaved inverter at a particular power level is based on the information of optimal efficiency; which is obtained from the power versus efficiency graph. Detailed calculations of peak current reference have been carried out for the various operating modes of the interleaved flyback converter based micro-inverter system; followed by simulation results for the proposed control scheme through Matlab-Simufink software. Experiments are underway and the results will be presented in the final paper.
