Interleaved Flyback Micro Inverter Based Solar Photovoltaic Power Generation System

PV generation is one of the fast growing renewable generation system to avoid the energy shortage. The micro-inverter system is best option for maximum energy harvest from each solar panel and easily we can expand the installed capacity. Now a day it is playing big role in rooftop system. These inverters divided as a single stage and double stage micro inverter. Compare to single stage double stage system having high efficiency with regulated waveforms. Interleaved flyback boost converter topology is used for improve the efficiency. Converter is high step up dc-dc boost with MPPT, MPPT is used to vary the duty cycle to generate maximum power from each panel both healthy and partial shading condition. MPPT voltage range from 27 V to 45 V, for 200 W, lower maintenance cost and higher energy yield with open-circuit voltage below 45 V. Micro-inverter PV system can achieve up to 25% lower energy cost compared to the conventional central inverter system
