Multilevel inverters are a new family of converters for dc-ac conversion for the medium and high voltage and power applications. In this project, two new topologies for the staircase output voltage generations have been proposed with a lesser number of switch requirement. The first topology requires three dc voltage sources and ten switches to synthesize 15 levels across the load. The extension of the first topology has been proposed as the second topology, which consists of four dc voltage sources and 10 switches to achieve 31 levels at the output. Both topologies, apart from having lesser...

This Book reviews the design and evaluation of different DC-DC convertertopologies for Battery Electric Vehicles (BEVs). The design and evaluation of theseconverter topologies are presented, analyzed and compared in terms of output power,component count, switching frequency, electromagnetic interference (EMI), losses,effectiveness, reliability and cost. Thus, a bidirectional DC-DC converter with a widevoltage-gain range is desired for energy storage systems to connect a high-voltage batterywith a low voltage motor. The interleaved switched-capacitor DC-DC converter is used tointerface the...
