ABSTRACT:
In a switched-mode power supply a coil is periodically connected across an input voltage by means of a switching element. The switching element is turned off when the voltage across a sensing resistor in series with the switching element exceeds a given threshold. The threshold is reached sooner when the input voltage increases. This effect is compensated by an inductive element in series with the sensing resistor, through which inductive element the same current flows as through the sensing resistor.
