Abstract
A method for fault correction in a power converter circuit arrangement. The power converter circuit arrangement has a plurality of switch modules which consist, for their part, of a parallel circuit of semiconductor chips. The semiconductor chips are interconnected via connecting wires, preferably bonding wires. If, because of a defect, a chip forms a short circuit, the connecting wires of chip are severed by specific current pulses. The advantage resides in that a short circuit of an individual chip does not put the entire circuit arrangement out of operation.
