Abstract

Multilevel inverter has become most popular over the years in the area of high power medium voltage energy control. With the recent advancement in Power semiconductor switches, multilevel inverter fed induction motor drives are extensively used in industries. Common mode voltage (CMV) is the voltage measure between star point of load and system ground. CMV is produced in inverter causes current to flow through bearings which may cause premature failure of the motor bearings. This paper presents the reduction of CMV in Diode Clamped multilevel Inverter using multicarrier SPWM technique. A MATLAB Simulation of diode clamped multilevel inverter is presented by applying different multicarrier modulation techniques. CMV and THD are investigated.
