| Zusammenfassung: | Method for improving the linearity of an inductive device (110) with a magnetic core (11), comprising the steps:Operating the inductive device (10) by an electrical main operation signal with a main operation frequency (fm) producing a magnetic main operation field in the magnetic core (11);Providing an alternating electrical bias signal with a bias frequency (fb) higher than the main operation frequency (fm) producing a magnetic bias field in the magnetic core (11) superimposed to the magnetic main operation field, such that non-linear and/or hysteresis effects in the magnetic core (11) are shifted from the main operation frequency (fm) to the bias frequency (fb). |
