A new reduced switch count seven level cascaded multilevel inverter for BLDC motor

In this paper, a new seven level reduced switch count inverter is introduced for BLDC Motor. In conventional H-bridge multilevel inverter to produce a seven level twelve 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. It dramatically reduces the switches for high number of levels that reduces the switching losses; cost and low order harmonics and thus effectively decreases total harmonics distortion.
