A Novel Method of Multilevel Inverter for Solar based PV Cells

Supplying electrical power to consumers is essential in every place for development. Owing to limits and limited availability of fossil fuels, there is a global search for advancements in power generation systems based on renewable energy. However, the supply of quality power is very hard factor in power system. Fortunately after coming of power electronics devices, the transmission and conversion of electrical power becomes very easy with proper selected controllers according to our requirements. The concept of multilevel inverters is popular among many power electronics devices. Applications of multilevel inverters in renewable energy based power generation systems are popular day by day with new technologies. However, the main drawback in multilevel inverters is increasing number of switches with increasing level. Moreover, the controlling techniques also become complicated by increasing level in multilevel inverters. Hence the reduction in number of switches is required to configure multilevel inverters to achieve the better response. The new configuration of multilevel inverter along with novel controller for Photovoltaic (PV) based power generation system is proposed in this paper. The voltage at load can be controlled with proposed controller, hence, this configuration can be used in many places where required controllable voltage applications. The extensive MATLAB/Simulink based results are presented to validate the proposed system.
