Design and Simulation of a Chopper Series for a Photo-Voltaic Generator Functioning at its Maximum Power

Static converters are used in various fields of the conversion of electrical energy. The significant development of electric power switches and variety of design techniques of control and regulation circuits provide very advantageous solutions for the congestion, reliability, performance and maintenance of converters. This work focuses on the study and simulation of a chopper Series, and its association with a photovoltaic generator for the purpose of a Maximum Power in Operation issued by the latter. The principle of the chopper control is based on the variation of the duty ratio, based on a percentage of the open circuit voltage of a solar cell driver. The operation control system helps the photovoltaic system to function at its maximum power.
