Abstract
An overvoltage protection circuit for a load having a determined resistance value is connected to a supply line with a predetermined polarity. An overvoltage detector is connected across the line. A first switch, normally on, is located in series with a conductor of the line and is controlled (i.e. switched to the off state) by the detector. A second switch, located in series with a resistance having the same determined value R, is disposed between the line conductors and is controlled by the detector in a complementary manner to the first switch.
