An integrated filter and controller design for direct matrix converter

A direct matrix converter working as a regulated voltage supply unit for power system (synchronous) applications has been considered in this work. Input filters design is initially presented where based on ripple attenuation, allowable regulation, losses and reliable commutation, certain boundary values are derived. This is followed by output filter design and thereafter for controller design, the effect of a chosen filter parameters on the dynamic performance has been investigated. Thereby a design oriented tool is obtained by which an integrated approach towards overall system design becomes possible. Finally experimental results on a 6 kVA prototype are presented to validate the analysis.
