Embedded system for single phase to three phase converter

Abstract

This paper proposes design of three phase induction motor control using single phase input and GSM. It is wireless speed control technique which is GSM based. Wireless technique proves to be economical and reliable power is increased. In constant V/Hz method, it is necessary to maintain a quantitative relation between magnitude and frequency of the voltage applied to mechanical device of a motor. This helps to maintain an approximately constant level of magnitude of magnetic field in the stator throughout operating range. Thus, it is possible to maintain capability of producing maximum constant torque. Switching power converter provides energy to a motor. This energy is controlled by Pulse Width Modulated, a signal by applying it to the gates of the power transistors. PWM signals are generated pulses with fixed frequency, magnitude and variable pulse width. Turn on and turns off intervals the transistor occur when a PWM signal is applied to gate of a power transistor.
