Abstract
In this paper, various control methods for two-phase winding capacitor induction motor drives are proposed. Comparative performance evaluation of three different control techniques with the same fundamental voltage is given. For the first condition, the motor is fed by a sinusoidal power supply provided from a synchronous generator for both main and auxiliary windings without phase shifting of the supply voltage (conventional method). For the second condition, the motor is fed by the designed half-bridge inverter with 90 degree current phase difference for each winding. The voltage sources of both windings are regulated by V/f control scheme. Like the second case, the last condition provides constant maximum current of the auxiliary winding and variable current depending load torque of the main winding. All experimental results are compared and discussed.
