摘要：
A circuit for detecting voltage variations in relation to a set value, for devices, such as a power supply circuit, comprising an error amplifier fed back by a compensating capacitor which, under steady state operating conditions, is not supplied with current, and, in the presence of transient output voltage (V.sub.o) of the device, is supplied with current (DI) proportional to the variation in voltage, the circuit comprising a current sensor connected to the compensating capacitor for detecting the current (DI) through the same; and the output signal of the sensor preferably being supplied to a circuit for limiting the variation in output voltage which, in the event the voltage variation exceeds a given threshold value (V.sub.R1), activates a control stage connected to the output of the device.
