  • Patent number: 5164890
    Abstract: A current sharing circuit for each of a plurality of parallel coupled power conditioners, each current sharing circuit for each power conditioner having a filtering circuit responsive to a voltage signal representative of the input current to the associated power conditioner for providing an averaged signal indicative of the average load current for the associated power conditioner. The averaged signals for all of the current share circuits are summed at a summing node to provide a reference voltage signal indicative of the average load current for the parallel coupled power conditioners. Each current share circuit further includes a differential circuit for providing a difference signal indicative of the difference between the average load current and the averaged signal, and an output circuit for adding the difference signal with the associated power conditioner output voltage to provide a feedback signal for the error amplifier of the associated power conditioner.
