Abstract
A reversible matrix converter circuit is provided with n levels per phase including n conversion arms exhibiting on one side n ends for generating or receiving respectively n intermediate DC voltage levels, and exhibiting on another side n ends linked at a common point of AC signal input or output. The circuit includes: —two external arms linked respectively to the highest level of positive voltage and to the lowest level of negative voltage, these two external arms each having a single IGBT transistor or two power transistors, linked by their emitter, —two IGBT power transistors, linked in series by their emitter on each of the n−1 internal arms, —filtering capacitors disposed respectively between the n intermediate voltage levels.
