Abstract :
A novel approach is proposed to extend the range of speed control and to eliminate the harmonic contents of the output voltage of the two-phase inverter-fed induction motor. These are both disadvantages of a conventional two-step driving system. Phase-difference control is used to extend the range of speed control and to simplify the driving circuit. A microprocessor-based PWM technique is used to eliminate the harmonic content of output voltage. The algorithm for phase-difference control is presented. The performance of a two-phase induction motor run by the phase-difference control method is analyzed
