MODULATON AND CONTROL STRATEGIES OF MATRIX CONVERTER

Abstract

This paper presents the different kinds of power electronic converters are introduced and then modulation
and control strategies of matrix converter. The matrix converter is an array of controlled semiconductorswitches that
connects directly the three-phase source to the three-phase load. The main element of Matrix converter is the fully
controlled four quadrant bidirectional switch, which allows high-frequency operation. And also the desirable features of
matrix converter is generation of load voltage with arbitrary amplitude and frequency; sinusoidal input and output
currents; operation with unity power factor for any load; regeneration capability. This paper presents the state-of-theart view in the development of this converter, starting with a brief historical review. Some new control methods of power
bidirectional switches integrated in a single module are also presented. The results shows some practical issues related
to the practical application of this technology, like overvoltage protection, use of filters, and ride-through capability.
