Matrix converter

摘要

Nine bidirectionally blocking power components are attached on a substrate in the form of a three-row matrix. The power components are attached between three respective current conductors arranged parallel to each other above and below the power components. The current conductors above the matrix proceed at a right angle relative to the current conductors under the matrix. The interconnects to the gate and auxiliary emitter terminals are situated on or in a thin insulating printed circuit board or film and are secured to the corresponding contacts of the chips in recesses of the current conductors.
