POLARITY REVERSAL PROTECTION CIRCUIT FOR ENERGY SOURCES

摘要

The invention relates to a polarity reversal protection circuit for energy sources, especially for car batteries, which is connected between an energy source and at least one consumer (3) and/or at least one generator (4). Said polarity reversal protection circuit is to prevent the polarity reversal current from flowing through the connected systems, so that said systems cannot be damaged in the event of a polarity reversal. Said polarity reversal protection circuit comprises means for identifying whether the two poles (1, 2) of the energy source are connected to the corresponding connection points of the consumer (3) or generator (4), and means for decoupling the energy source from the consumer (3) or from the generator (4), if the two poles (1, 2) of the energy source have been reversed during connection to the consumer (3) or generator (4).
