Hybrid Multi Modular Converter For 25 Level Converter

Abstract

   Modular multi level converters (MMC) are gaining importance day by day due to their inherent advantages of bidirectional capability, reduced switching loss. MMCs have become one of the best choices for electric vehicles (EV) and storage based electric vehicles as these converters have the ability of conduction in both the directions with bidirectional switches. One of the major issues of concern of an EV is that the storage of energy, as these vehicles battery storage with large capacity and these batteries required to be charged continuously. This feature of EV makes usage of MMCs as an attractive solution. The output available across a MMC is stepped sine wave. As the number of steps increases nearness of output voltage with a sine wave is increased, but this is not true in case of a Sinusoidal Pulse Width Modulated Inverter.
