| Abstract |
This paper presents equations for calculating the losses that
arises in an inductor at ac-induction. A system for fast
measuring of the inductor parameters, inductance L and
equivalent series resistance RLS, is also presented. From RLS
the total losses of an inductor can be calculated. The system
makes use of the oscillation between the capacitor and the
inductor in a LC-circuit to determine the parameters. With
known C, the resonance frequency of the oscillation
determines the inductance L. The damping of the oscillation
due to resistances in the circuit determines the series
resistance RLS. When the series resistance is known the total
average loss of the inductor can be derived as RLS Irms
