Space Vector Controlled Single-Phase to Three-Phase Direct Matrix Converter Drive

This paper presents a study of space vector modulated single-phase to three-phase (1 × 3) direct matrix converter (DMC). In the direct matrix converters, DC link is not present; therefore, switching ripples get reflected in the output of matrix converter, and to attenuate these ripples, input as well as output filters are essential for better voltage regulation and performance of the converter. Filter design which is either of input source side or load side is based on some important operating parameters in the induction motor drive control. The design of filters considering source side as well as load side parameters is also described in the paper. MATLAB/Simulink environment is used to simulate the control strategy of the single-phase to three-phase direct matrix converter with a three-phase induction motor model; feasibility and validity of the converter are also discussed.
