In high performance drives where it is desirable to exploit the usefulness of reluctance torque and machine saliency, permanent magnet synchronous brushless motors are machines of choice. However, speed control of these machines especially in the flux weakening region becomes mo…

The high switching frequency associated with pulse width modulation (PWM) that is commonly utilized in controlling the motion of high performance motor drive systems leads to motor iron losses. In addition to fundamental component, line voltages generated by voltage source inver…

Space vector pulse width modulation is the most preferred for three phase voltage source inverter. It has better total harmonic distortion and higher DC bus utilization compared to other pulse-width modulation techniques. The three-level voltage source inverter is preferred over…
