Abstract: In many cases, the influence of temperature on the quality of a coil has a disturbing effect. Therefore, a coil inductance is produced such that the influence of temperature on the quality of the coil is substantially compensated for in a particular range of the system frequency. To this end, a second coil having a second quality value Q2 is magnetically coupled in series to a first coil having a first quality value Q1. Moreover, the two coils are selected in such a way that for a particular range of the system frequency f, the quality value Q1 decreases as the temperature T increases and the quality value Q2 increases as the temperature T increases. A coil conductor for the first coil made of litz wire and a coil conductor for the second coil made of solid wire may be used to create such a temperature dependence.
