Control ot two-phase induction motor by changing the phase difference angle

摘要

A phase-difference angle (PDA) controlled pulse width-modulated (PWM) inverter instead of phase voltage modulation and/or frequency changing is proposed to control the speed, and position of a two-phase induction motor. Several characteristics of a two-phase. induction motor driven by the PDA inverter are studied to verify the improvement of the motor performances. Also, speed, and position tracking are achieved using the proposed control technique.
