Multilevel Inverters Implementation with Voltage Restore Process

N Praneeth, S Swapna, Yeruva Susmitha
For High power, high voltage applications modern ages multilevel inverters are widely used. They provide better operation as well as effective efficiency rather than conventional two level inverters which differs in harmonic distortion, lower electromagnetic interference with large dc link voltage ratings. In multilevel inverters have problems in the sequence of number of components, complex pulse width modulation control method and voltage balancing problem. In this paper new topology is

Where this method need of few more components other than conventional inverters, require fewer carrier signals and gate drives. Especially for High power output voltage levels the overall cost and complexity are reduced greatly. A prototype of seven level inverter is discussed with simulation of MATLAB which tested with simulation results.
