In this paper, new reduced switch count technique is introduced to construct a multilevel inverter topology which reduces the number of switches used in the system. Sinusoidal pulse width modulation is used to control proposed inverter. In conventional H-bridge multilevel inverter to produce a seven level ten number of switches are used. Due to involvement of high number of switches thereby the harmonics, switching losses, cost and the total harmonics distortion is increased. This proposed topology involves only eight numbers of switches.
