Abstract: A wind-solar hybrid system is a reliable alternative energy source because it uses solar energy combined with wind energy to create a stand-alone energy source that is both dependable and consistent. Renewable power systems as distributed generation units often experience big changes in the inverter input voltage due to fluctuations of Wind energy resources. However, when a very high boost gain is demanded, the duty cycle may come to its extreme and large duty cycles causes serious reverse- recovery problems. This paper proposes a three phase single stage boost Inverter with space vector modulation, by introducing hybrid system containing Permanent magnet Synchronous Generator(PMSG) along with Photovoltaic cell. The MaximumPower Point Tracker (MPPT) including coupled inductor into the three phase bridge inverter can realize a high boost gain and output a stable ac voltage. The single- stage operation of the converter may lead to improved reliability and higherefficiency.
