摘要
In this paper, a 11-level inverter fed induction motor (IM) speed control is presented. A Scalar speed control method is used to control speed of IM. The suggested inverter topology significantly reduces the switching device count. The presented work uses a 11-level inverter to control the speed of motor. This topology required eight switches for the 11-level inverter output voltage generation. Variable frequency multicarrier PWM is utilized for controlling the output voltage of inverter. The IM speed control is performed in both open loop and closed loop scalar control methods. In both speed control methods, v/f ratio and ripples in the torque of the IM are maintained constant. PI controller controls speed regulation of induction motor. The suggested converter topology fed induction motor drive has been simulated in a MATLAB environment.
