【 摘 要 】

The aim of the project is to design and simulate a single phase five level inverter with coupled inductor using modified sinusoidal PWM (MSPWM) techniques. There are many multilevel inverter topologies with multiple DC sources and multiple DC capacitors exist which leads to the problems of bulky transformers for multiple sources and balancing of the DC capacitor voltages. The number of switching devices used in the existing methods is more. This project work proposes a multi level inverter topology with one DC source and eliminates the problem of DC capacitor voltage balancing. The feed-forward control method and design considerations are provided. The complete circuit is simulated employing MATLAB-Simulink and the results obtained verify its operation.
