New Modular Multi Level Full-Bridge Inverter for Renewable Sources

Abstract

In this paper a multi-level inverter is developed and applied for injecting the real power of the renewable power into the grid to reduce the switching power loss harmonic distortion and electromagnetic interference caused by the switching operation of power electronic devices. Here a dual buck configuration with full bridge inverter is used for the MLI implementation. Moreover, its control circuit is more complicated. Thus both the performance and complexity should be considered in designing the multilevel inverter. However interest in the multilevel inverter has been aroused due to its advantages of better power efficiency lower switching harmonics and a smaller filter inductor compared with the conventional half-bridge and full-bridge inverters. the operation and design of the Boost Converter is described in a very precise manner. Also the simulation of the Boost Converter in MATLAB and the corresponding output waveforms are done.
