Abstract
In order to measure a choke current through a choke, a flux density of a magnetic field which is emitted by the choke is consecutively measured at a sampling rate at a location which is fixed in relation to the choke. A magnetic bias of the choke is ascertained from the measurement values of the flux density at a known choke current which occurs during operation of the choke, wherein the choke current is known only in longer time intervals than the inverse value of the sampling rate during measurement of the flux density. The actual choke current is determined from the actual measurement values of the flux density taking into account the ascertained magnetic bias.
