Abstract: Multilevel converters are widely used due to its high efficiency, low harmonics and also its output waveform is almost similar to sinusoidal shape. There are many topologies developed for multilevel converter each of them has various advantages and disadvantages. In this paper a new topology is proposed which is a combination of conventional multilevel topology and H-bridge circuit having advantages of both. Here a 7 level multilevel inverter derived from the proposed topology is explained for analysis.

Keywords: Multi-level converter, 7 level inverter, gate drive circuit, charge pump circuit.
