Abstract:
1. Apparatus for the transfer of electric power produced by at least one multi-phase alternating-current generator ( 1 ) or generator unit into at least one multi-phase alternating-current power network (U u , U v , U w ), said apparatus comprising at least one control unit ( 4 ), at least one non-controlled rectifier bridge ( 2 ), a direct-current intermediate circuit and at least one controlled inverter bridge ( 3 ) for supplying d.c. power into an alternating-current power network said inverter bridge ( said control unit controlling the semiconductor switches (V in the upper branch, the switch in each phase conducts substantially as long as the instantaneous value of the network phase voltage (U in the lower branch, correspondingly the switch in each phase conducts substantially as long as the instantaneous value of the network phase voltage (U wherein the rectifier bridge ( the direct current output from the rectifier bridge (
