Comparison of five leg inverter and five phase full bridge inverter for five phase supply

Abstract

The main purpose of the inverters is to transfer power from a DC source to an AC load. Inverters are widely used in motor drives, un-interrupted power supplies (ups), appliances run from an automobile battery and photovoltaic utility grid interface. This paper describes a comparative study of performance between the five leg inverter and the five phase full bridge inverter. These inverters are used to feed the five phase induction motor. Now-a-days, the thrust is on research involving multiphase (more than three phase) due to their intrinsic benefits over the conventional systems. When the motor is fed by three phase supply, the undulation content is found to be high. However, this undulation content is smoothened by using multiphase systems. Therefore the applicability of multiphase systems is explored in electric power generation, transmission, & utilization.
