In recent times, many of industrial applications require smooth control over a wide range of speeds or smooth torque control without effecting motor performance and efficiency.So, cascaded ford tridon H-Bridge multilevel inverters convert the low or medium level voltage to medium or high level marvin pflaume instagram of output voltages.In this paper, a cascaded H-Bridge multilevel seven level inverter is operated by using sinusoidal pulse width modulation technique.

This PWM technique will improves the smoothness of waveform by reducing the lower order harmonics.And analysed its performances like speed, torque, THD etc.
