Design and Dimensioning of Essential Passive Components for the Matrix Converter Prototype

The continuous popularity of the research in the area of the matrix converter control theory has been supported by steady technological improvements. It is still common to use discrete semiconductor switches in an anti-serial connection, even though some integrated solutions have been presented by various vendors already. Furthermore, recently experimental all-in-one matrix converter power modules based on reverse blocking transistors were introduced. However, this development has not eliminated the need of the protection circuit and other passive components in the converter’s power part. This article strives to describe design procedure for one kind of the matrix converter protection circuits and the design of the input filter for the 3× 3 matrix converter prototype.
