ABSTRACT:
A converter circuit arrangement is specified which is constructed to have a particularly low inductance. This is achieved by the circuit area of the commutation circuit being kept as small as possible. A circuit area which is as small as possible is achieved by the branch modules and switch modules of a phase module being arranged either in a U-shape or in a meandering shape. The branch modules can be arranged either parallel to or at right angles to a main direction, between the positive and negative connections and the load connection. In addition, it is advantageous if the power semiconductor switches and the reverse-connected parallel diodes and freewheeling diodes are arranged in separate stacks which are held together by means of a clamping-in device.
