Single-phase matrix converter

A topology of a single-phase ACIAC 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 anld 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 50V (rms), 50Hz, supplying a paissive R, L load operated at lOOHz, was constructed. Satisfactory agreement between simulated and laboratory results was observed.
