Svpwm Technique for Four-pole Induction-motor Drive with Single Dc–link Using a Quad Two-level Inverter

In this paper a new SVPWM technique is implemented along with multilevel inverter topology for a four-pole induction-motor drive; which is constructed using the induction-motor stator winding arrangement. In this process we are comparing with the conventional five-level inverter topologies so we are a single dc source with a less magnitude therefore, the power balancing problem are reduced. As this configuration usesa single dc source. and it also provides path for zero-sequence currents because of the zero-sequence voltages present at the output side, which will flow through the power electronic switches and motor phase winding. By using SVPWM Technique generates less harmonics distortion at output voltage and current and voltage utilization will more compare to other PWM technique. In this paper we are implementing SVPWM technique with the quad two level inverter topology is proposed and verified using the simulation results.
