This paper describes sinusoidal pulse width modulation of the voltage impressed to the stator of an induction motor for direct control of torque and stator flux. Instantaneous voltage vectors applied by an inverter have redundancy characteristics which provide some flexibility for selecting the inverter switching modes. By using this switching freedom,(More)
This paper presents a direct current controlled pwm method for control of four-switch, three phase BLDC motor. The main features of this converter are twofold: the first is the reduction of switches and freewheeling diode count; the second is the reduction of conduction losses. For effective utilization of the developed system, a novel direct current(More)
Multiphase variable speed drives are nowadays serious contenders for various applications. The multilevel (predominantly three-level) voltage source inverters (VSIs) and converters have become industrially accepted technologies in three-phase systems. In recent times, attempts have commenced to integrate multilevel VSIs and converters with the multiphase(More)
