Abstract
This paper presents a soft starting control scheme of a capacitor start and run type single-phase induction motor(SPIM) using a PWM AC Chopper control technique to control an amplitude of the motor starting current. The actual current of the motor during start up is used as a feedback signal for comparing with a setting value. The error, then, is sent to a PI controller. The output of the PI controller is compared with a carrier to generate a PWM signal. The MATLAB/Simulink is used for simulations. The results of the simulations are the amplitude of the motor starting current in accordance with the setting value which is around 150-200% of the rated motor current, the energy consumption during the start up and the ripples in the electromagnetic torque. It is found that the control scheme proposed in this paper is effective and can be considered as an alternative in a starting method for SPIM. © 2013 IEEE.
