  • Patent number: 3974397
    Abstract: Disclosed is a multi-source rectifier system for providing DC power to a load from a plurality of high impedance AC electrical sources connected to a multi-source high voltage transmission system. The system comprises a parallel arrangement of high impedance AC current sources each connected in series with a respective bridge rectifier, the positive output terminals of all bridge rectifiers are connected in parallel to the positive side of a load. The negative output terminals of all bridge rectifiers are connected in parallel to the low side of the load. The individual high impedance AC current sources are completely isolated from one another through their series connected bridge rectifiers, making it possible to simultaneously supply current from more than one high impedance AC current source to the load without significant circulating currents among the sources.
