ABSTRACT:
Device for controling an electrical motor mounted on the crossarm of a bridge circuit whose motor current is controllable with semiconductor components formed in a first bridge branch by an electromagnetic switching device and in a second bridge branch by two serially switched, opposite-phase timed semiconductor switches. The opposite-phase timing of both semiconductor switches creates an active freewheeling branch, thereby making a freewheeling diode unnecessary.
