Single-phase matrix converter

Abstract

A topology of a single-phase AC/AC direct converter is presented. The circuit composed from four ideal power switches is used as a frequency step-up converter. The equations of the proposed converter are developed, its switching angle pattern is calculated and the dynamic behaviour of the system is simulated. Using a power MOSFET and four Schottky diodes the basic power switch is assembled and a converter fed from 50 V (rms), 50 Hz, supplying a passive R, L load operated at 100 Hz, was constructed. Satisfactory agreement between simulated and laboratory results was observed.
