Abstract

This paper presents a new method to improve the efficiency and torque characteristics of a single-phase induction motor. By using this method, the efficiency and starting torque of the motor are increased. The starting capacitor and the centrifugal switch can be eliminated here. Only a running capacitor is used. A prototype system which consists of some simple hardware circuits and a TMS320C40 digital signal processor system has been implemented. Several experimental results can validate the simulated waveforms. This paper proposes a new direction in improving the performance of the single phase induction motor system
