Multi Level Converters for Medium Voltage Applications

In today's era, high power equipment of megawatt level is used in industries. In this paper, the authors focus on basic introduction to the three configurations of multilevel inverter and the fabrication of one of the configuration. Three topologies are proposed for voltage balance in multilevel converters i.e. diode-clamp, flying capacitors or capacitor clamped and cascaded inverters with separate DC sources. The circuit topologies, advantages, disadvantages of all the three configurations and the circuit diagram for hardware fabrication of diode clamped three level single phase inverter is discussed.
