Abstract
The invention relates to a device () for measuring a current through a choke () of a voltage converter () comprising an integrator circuit (), an amplifier circuit and an NTC resistor (). The amplifier circuit comprises an inverting and a non-inverting amplifier input connection () and an amplifier output connection (). The non-inverting amplifier input connection () is supplied with an amplifier input signal according to an integrator output signal. A voltage signal characterising the current through the choke () is applied at the amplifier output connection () of the amplifier circuit. The NTC resistor () is arranged in the feedback path of the amplifier circuit between the inverting amplifier input connection () and the amplifier output connection ().
