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

Abstract

Original scientific paperThe 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.Key words: Matrix converter, Input filter, Protection circuit, Direct frequency converter Dizajn i dimenzioniranje ključnih pasivnih komponenata prototipnog matričnog pretvarača. Dugotrajna popularnost istraživanja u području upravljanja matričnim pretvaračima podržana je trajnim tehnološkim napretkom. Još se uvijek učestalo koriste diskretne poluvodičke sklopke u antiserijskom spoju, iako postoje integrirana rješenja. Unatoč nedavno predstavljenim prototipnim sve-u-jednom matričnim pretvaračima zasnovanim na reverzno blokirajućim tranzistorima, još nije eliminirana potreba za zaštitnim krugom i drugim pasivnim komponentama u energetskom dijelu pretvarača. Upravo je cilj ovogačlanka opisati korake u sintezi jedne vrste zaštitnog kruga matričnih pretvarača i ulaznog filtra za prototip matričnog pretvarača dimenzije 3 × 3.Ključne riječi: matrični pretvarači, ulazni filter, zaštitini krug, direktni frekvencijski pretvarači
