A Novel Minimized Switch Two-Phase Matrix Converter for Driving Two-Phase Induction Motor

In this paper using matrix converter theory and B4 inverter concept, a novel minimized switch two-phase matrix converter for driving two-phase induction motor is proposed.The proposed converter, which is simple and compact, has less switches compare to prior topologies and its input voltage issingle-phase which is available in commercial and domestic applications. A sinusoidal pulse width modulation (SPWM) switching strategy is proposed to provide sinusoidal outputwaveforms with two-phase loads without any intermediate dc stage. The proposed minimized switch two-phase matrixconverter and switching strategy can generate the two-phase output voltages/currents where the amplitudes are independentlycontrolled and the phases difference is fixed at 90º. Detailed analysis is provided for proposed converter with a three-phase balanced R-L load, also proposed converter is used for driving two-phase induction motor. Simulation results verify validity and performance of the proposed converter
