Three Phase Induction Motor Drive Using Single Phase Inverter and Constant V/F method

Abstract

The induction machine is used as the most common motors in different applications. It is the workhorse of industry. But they require much more complex methods of control, more expensive and higher rated power converters than DC and permanent magnet machines .This paper presents control of a three phase induction motor using single phase inverter with constant volts hertz control (V/F) method and pulse width modulation. Frequency control with flux proportional to V/f and voltage proportional to the speed seems to be the best solution. PWM gives a high quality output voltage. Single phase inverter output gives a better feed to the induction machine without extra components needed on the motor and also produces a higher starting torque and reduced speed pulsation amplitude.
