Design and Development of Multi Level Inverter

Abstract

Multilevel inverter becomes popular because of its high power, high voltage application. However it has some disadvantages such as increased number of components, complex control method and voltage balancing problems. In this paper, we proposed a new topology having level modules and H-bridge inverter, and reverse voltage technique is adopted for load. APOD based PWM technique is used to generate pulses for switches. This method requires less components for operation and THD is reduced to a greater level. For voltage THD is 8.12% and for current THD is 0.53.Simulation is done using SIMULINK/MATLAB software. Index terms’-bridge inverter, multilevel module, THD
