DESIGN AND SIMULATION OF A SOLAR-WIND STAND-ALONE SYSTEM WITH A SEVEN-LEVEL INVERTER

During an energy conversion process, the total harmonic distortion and losses will increase while its power stability decreases. Multilevel inverter technology can be utilized to alleviate shortcomings of conventional inverters. These technologies have become recognized as cost-effective solutions for a wide range industrial applica-tions. Reduced component lower switching losses, well improved output voltage current wave-forms are first advantages this design. In multilayer inverters, elimination components in is crucial. This paper proposes system that consists three different renewable sources. Two them PV solar systems third wind turbine simulated MATLAB Simulink. Seven-level inverters based on switch reduction techniques proposed paper. The design verified absence produce five levels contingency systems.
