Review on VSI Switch Fault Tolerant Control Systems for ...Existing fault tolerant control inverter topologies high output power to size ratio, constant torque over a wide are also reviewed and compared based on EV application speed range, fast dynamic response (due to the permanent requirements.
Variable Speed Drive (VSD) for Irrigation Pumpingincluding variable speed and the potential energy savings. Often, changing the pump's speed is the most efficient method of control. When a pump's speed is reduced, less energy is used by the pump's power unit and therefore less energy needs to be dissipated or bypassed.
SixStep VSI Induction Motor Drive MathWorksInstead, the speed set point is used only to determine the motor voltage and frequency applied by the sixstep inverter in order to maintain the (V/F) ratio (or the motor flux) constant from 0 to the nominal speed.

Review on VSI Switch Fault Tolerant Control Systems for ...high output power to size ratio, constant torque over a wide speed range, fast dynamic response (due to the permanentmagnet rotor), lower maintenance needs (due to the absence of brushes), noiseless operation and high operating speed ranges are the main advantages of PMSMs over other motor types for passenger EV applications [2].
Speed Control of Three Phase Induction MotorWhen the speed control of three phase induction motor is done by adding resistance in rotor circuit, some part of power called, the slip power is lost as I 2 R losses. Therefore the efficiency of three phase induction motor is reduced by this method of speed control.
