Simulation and speed control of induction motor fed by indirect matrix converter

Abstract: 

A matrix converter is used as an alternative AC–AC power converter that has received wide research concentration as an alternative scheme to fixed AC–DC–AC converter. To convert the energy from an AC source to an AC load without the need of bulky and limited-lifetime energy-storage elements matrix converters are preferred. This paper presents a simulation of speed control of Induction motor fed by Indirect Matrix Converter (IMC) using v/Hz technique by space vector PWM technology. Out of the several methods of speed control of an induction motor such as pole changing, frequency variation, variable rotor resistance, variable stator voltage, constant V/f control, slip recovery method etc., the closed loop constant V/f speed control method is most widely used. The simulation results were carried out for very sparse indirect matrix converter fed induction motor drive and the performances of indirect matrix converter is analyzed and verified using the response obtained through Matlab/Simulink.
