Abstract

Grid connected solar system uses to have converters Circuits followed by two levels: A DC/DC boosters and PWM Inverter. This combination of converters leads to decrement of Quality and efficiency of electric power, In this paper the author Propose a single phase 13- level photo voltaic (PV) inverter for Grid connected solar system with A novel pulse width-modulated (PWM) control scheme. The fast variations of solar radiation can be compensated by Digital proportional-integral controller. The inverter offers less total harmonic distortion and good power factor. The proposed system offers improved performance over five level inverters and is verified through simulation
