Comparative Analysis of THD in Symmetrical and Asymmetrical Cascaded H-Bridge Seven Level Inverter

To read the full article Peer-reviewed Article PDF image


In this paper , the performance of symmetrical and asymmetrical single phase cascaded h-bridge seven level inverter with respect to harmonics content and voltage stress across the switch with photovoltaic cell as its input source is simulated by using MATLAB/Simulink. Multicarrier pulse width modulation control technique is adopted in the firing circuit to provide an acceptable control in the inverter output voltage. Hence we could achieve the improved efficiency of the system The simulated output shows very favorable result.
