© 2014 IEEE. Direct matrix Converter is considered as a powerful tool for AC/AC power conversion providing AC output voltage and frequency control It also has many features such as a bidirectional power flow, a compact size and a direct conversion capability In this paper, matrix converter is used to convert a five phase input voltage into three phase output voltage with controlling output current amplitude and frequency. Five-to-three phase matrix converter is used to control a three phase induction motor. Using a five-to-three phase matrix converter enables using multiphase generation units and at the same times there is no need to change existing three phase loads. Predictive Torque Control (PTC) algorithm is used to control the induction motor fed by a matrix converter. The performance of the proposed speed control system is verified by a MATLAB simulation of a 4 kW induction motor fed by a five-to-three phase matrix The simulation results during different operation modes verify the validity of the proposed closed loop speed control method.
