Abstract

A limiting circuit, particularly for a power supply, includes a first reverse-polarized Zener diode connected and configured to limit a voltage between two output terminals depending on a first breakdown voltage, a second reverse-polarized Zener connected and configured to limit a voltage between two output terminals depending on a second breakdown voltage, a semiconductor switch coupled in series with the second Zener diode to open or close depending on a switching signal, a first shunt resistor coupled in a load path and with the first and second Zener diodes to carry the load current and the currents flowing through the first and second Zener diodes, and a comparating device configured to generate the switching signal depending on a voltage drop over the first shunt resistor.
