  • Charger connected to a load via a switching circuit to prevent an incorrect polarity connection
    Patent number: 6774607
    Abstract: The invention relates to an electronic circuit for a power supply device (1), in particular for a charger (2) for accumulators (3), in which the power supply device (1) is connected via input terminals (4, 5) to a power source (6), the power supply device (1) converting the supplied power from any voltage, in particular an AC voltage, into a DC voltage and this transformed power is forwarded via output terminals (7, 8) to a consumer (9), in particular the accumulator (3), in which, a switching element (10) is provided as a means of operating polarity reversal protection. The switching element (10) is disposed between at least one output terminal (7, 8) and a potential, in particular a negative potential, of the power supply device (1) and if a specific polarity appears at this output terminal (7, 8) the switching element (10) is connected through and if an opposite (incorrect) polarity appears it is switched off.
