| Abstract | ||
| This paper presents an approach for improving both the starting and running performance of the single-phase induction motor using a statically controlled capacitor. The control principle is based on a PWM switching for the auxiliary series capacitor using a pair of fast electronic switches. The proposed scheme ensures continuously varying capacitance of the auxiliary circuit. A d-q model for the single-phase induction motor operating under the proposed control has been developed and numerically analyzed. The optimum operating conditions for starting and running has been obtained. A laboratory set-up has been built and experimentally tested to examine the proposed control. Simulation and experimental results are compared and shown to be in good agreement. 1. INTRODUCTION Single-phase induction motors are widely used specially in domestic and office applications. They have the advantages of rugged construction, maintenance- free and low cost. The main problem of this motor is that it is inherently of no en annenhage | ||
