Abstract

The present disclosure relates to electric converters. The teachings thereof may be embodied in an electric converter to transfer an electric power of more than 3 kilowatts comprising a half-bridge with at least two parallel circuits. Each of the parallel circuits includes a plurality of semiconductor switches. Each of the parallel circuits includes at least two base circuits arranged next to one another on a common printed circuit board. Each of the respective base circuits includes one of the plurality of semiconductor switches and a gate driver circuit for the semiconductor switch. Each gate driver circuit is electrically connected to a gate of the semiconductor switch by a control line. In each of the parallel circuits, a shortest control line and a longest control line differ from one another with respect to length by no more than the factor of 1.5.
