Development of Space Vector Modulator for Three-Phase to Three-Phase Matrix Converter

Abstract

The matrix converter is an array of controlled semiconductor switches that con-nects directly the three-phase source to the three-phase load. This converter has several attractive features that have been investigated in the last two decades. This converter gives variable output frequency and variable output amplitude. In the last few years, an increase in research work has been observed, bringing this topology closer to the indus-trial application. In this report, varies modulation methods are reviewed and compared. The majority is given an overviewed, and the one, which employs simultaneous output-voltage and input-current space vector modulation is systematically reviewed. The mod-ulation algorithm is theoretically derived from the desired average transfer functions, us-ing indirect matrix converter approach. This report presents a new double-sided modula-tion strategy for matrix converters based upon an indirect conversion scheme which mod-els the matrix converter as two independent stages performing rectification and inversion. The new modulation strategy keeps the number of switching at a minimum. This space vector modulation for matrix converter is implemented in PIC18F452 microcontroller and compared with simulation results. The space vector modulation for matrix converter is implemented with the use of only one PIC18F452 microcontroller and some other hardware.
