Abstract: The matrix converters (MC), which are direct power electronic converters, are able to provide important benefits such as bidirectional power flow, sinusoidal input currents with adjustable displacement angle, and a great potential for size reduction. In this project, two kinds of novel but simple control strategies for current controlled matrix converter are proposed. These two methods have all major advantages of both space vector modulation (SVM) and hysteresis current control (HCC) control techniques, and can help to greatly reduce the system complexity compared to traditional SVM based matrix converter control system. Simulation results are presented to show the performance of both of these two HCC controllers for matrix converter. The behaviors of SVM technique and hysteresis current control HCC technique for matrix converter under abnormal input voltage conditions, in terms of unbalanced, non-sinusoidal and short duration voltage sag, have been investigated. The HCC technique has the inherent ability of preventing the disturbance at the gird side from propagating to the MC output side, and ensuring the drive performance of induction motor under abnormal input voltage conditions. Simulation results have been obtained to demonstrate their different output characteristics under abnormal input voltage conditions.
