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…mehr

Produktbeschreibung
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 switch count, exhibit the merits in terms of reduced voltage stresses across the switches. Therefore the new topology offers good flexibility in designing. To achieve better harmonic reduction and number of switch count a space vector modulation technique is chosen for controlling multilevel inverter.
