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

摘要

A matrix converter circuit with n symmetrical levels per phase including n conversion arms respectively supplied with n intermediate symmetrical voltage levels and connected at the output thereof to a common point generating an output current, characterized in that it includes: two external arms supplied respectively with the highest level of positive voltage and with the lowest level of negative voltage, these two external arms each including a single IGBT transistor, and two IGBT transistors connected in series by their emitter on each of the n−2 internal arms.
