Abstract
Transmitter or receiver resonant circuit for carrying out contactless power transmission via resonant inductive coupling to a receiver or transmitter resonant circuit, comprising a first capacitance and a first winding, the first winding comprising an inductance and a first resistance, the transmitter resonant circuit comprising a second capacitance of value C′ and a second winding, the second winding comprising a second inductance of value L′ and a second resistance of value R′, the transmitter resonant circuit having a natural angular frequency u>2 such that w=1/V(L′×C′) and a natural frequency fsuch that f=w/(2π), characterized in that the value of the second inductance varies in a predetermined manner.
