A Study on Performance of Single-Phase to Three-Phase Converter

In this paper, a direct conversion from single-phase to three-phase alternating current using thyristor switching device is proposed, and this system is proposed to remove several defects inherent in the device feeding from a single phase power, when the converter is used to an induction motor drive this system could achieve an excellent characteristics such as high starting torque and low starting current. The smooth output voltage wave form and sinusoidal input current could be obtained by replacing the conventional rectifier circuit with the convertor.
