Abstract :
An examination is made of the operation of split-phase induction motors from pulse width modulated (PWM) voltage source inverters. Splitting the phase windings leads to reduced voltage ratings for the inverter switches. The inverters are operated with space phasor based PWM. It is well known that with this technique, a three phase inverter can give a maximum peak fundamental of 0.577 V/sub DC/ for the motor phase voltage (with a circular trajectory for the voltage space phasor), as against 0.5 V/sub DC/ with sine triangle modulation.<>
