This paper emphasizes on different modulation techniques on a single phase extendable topology. The topology is analyzed for different levels of output voltage generated with a comparative study of voltage and current total harmonic distortion (THD) for various pulse width modulation (PWM) control strategies. The extendable topology uses receded number of dc sources and switching devices over the conventional cascaded H-bridge inverter, thereby reducing the circuit ramification and cost. The performance of the switching strategies for 7-level and 31-level is verified by simulation results. © 2017 IEEE.
