MULTI-LEVEL, MULTI-VOLTAGE MATRIX CONVERTER CIRCUIT AND METHOD FOR IMPLEMENTING SUCH A CIRCUIT

摘要

The invention relates to a matrix converter circuit having n symmetrical levels per phase including n conversion arms respectively supplied by n intermediate symmetrical voltage levels and connected at the output thereof to a common point generating an output current. According to the invention, said circuit includes: two external arms respectively supplied by the highest positive voltage level and by the lowest negative voltage level, said two external arms each comprising a single IGBT transistor, and two IGBT transistors connected in series by the emitters thereof to each one of the n-2 internal arms.
