Abstract:The main objective of this paper is to control the speed of an induction motor by using seven level diode clamped multilevel inverter. To obtain high quality sinusoidal output voltage with reduced harmonics. The proposed Scheme for diode clamped multilevel inverter is multicarrier SPWM control. An open loop speed control can be achieved by using V/ƒ method. This method can be implemented by changing the supply voltage and frequency applied to the three phase induction motor at constant ratio. The proposed syst… Show more
