Sinusoidal output voltage H-bridge multilevel inverters

Multilevel inverter technology has emerged recently as a very important alternative in the area of high power and medium voltage energy control. This paper carried out the analysis and simulation of H-bridge multilevel inverter. To control the output voltage modulation techniques like Sinusoidal Pulse Width Modulation, Multicarrier Pulse Width Modulation and Space Vector Pulse Width Modulation are applied. Finally, sinusoidal output voltage is achieved by incorporating a suitable filter.
