Improve of a Hybrid PV System Performances Based on MPPT Algorithm and Multi-level Converter

This work present an improvement of a Hybrid PV system performance based on the use of both MPPT algorithm and multilevel inverters. Inverters are an essential element in renewable energy production systems. Conventional inverters have several drawbacks such as overvoltage problems at the semiconductor terminal in high-power applications, and the obtaining of a non-sinusoidal voltage that is rich in harmonics. Multilevel inverter topologies can be arranged in many different combinations; among the popular multilevel inverter topologies are Diode Clamped Multilevel Inverters (DCMLI). Two types are studied and compared that are three and five Diode Clamped Multilevel Inverter (DCMLI). The modeling and the control of the PV system are developed and implemented in Matlab/Simulink environment. Simulation results are presented and analyzed up.
