摘要：A protection circuit for a parallel power system having at least two parallelcoupled voltage regulators is disclosed. The protection circuit includes at least twoisolation control circuits, each control circuit being coupled to a respective voltageregulator. Each isolation control circuit includes a current sense circuit for sensing currentpolarity at an output of the respective voltage regulator, and a controller for

automatically isolating the respective voltage regulator when an over-voltage conditionexists at an output of the parallel power system and a positive current polarity is sensedat the output of the respective voltage regulator. The at least two isolation controlcircuits isolate only a voltage regulator having positive current outflow during the over-voltage condition. In one embodiment, each isolation control circuit further includes anover-voltage detection circuit for detecting when the over-voltage condition exists at theoutput of the parallel power system.
