A Single Dc Source Based Cascaded H-Bridge 5- Level Inverter

P. Iraianbu, M. Sivakumar

This paper presents a cascaded H-bridge multilevel inverter for Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) application. These new type of inverter are suitable for the high power application due to that the synthesize waveform with better harmonics and output waveform. In this, two H-Bridge inverter are connected in series in which the second H-bridge inverter uses capacitor and this capacitor acts as a DC sources whenever the DC supply is absent the modified PWM techniques is to be developed to reduce the switching losses and also to reduce the total number of switches. To develop the model of the multilevel inverter, a simulation is done by using the MATLAB/SIMULINK software
