Intégration d’un Onduleur a Cinq Niveaux Dans Une Chaine Photovoltaïque

Abstract

The purpose of this memoir is to display the role of the multi-level inverter into the photovoltaic use. The NPC inverter, which converts DC/AC, should be chosen regarding the appropriate level Of voltage to obtain a good quality of energy that is made with a photovoltaic generator. De comparison of tow ,three and five-level inverters proves that the latter is the best in giving a goode result and taking shorter time. In sum, we have concluded that it’s necessary to increase the voltage level from three-level inverter into five-level inverter in order to get better results in photovoltaic field.
