Abstract
Official abstract text for this publication.
A circuit for inductively transferring electrical energy from a primary side to a secondary side has a primary-sided autoresonant power oscillator compensated in parallel having a primary inductivity and serially compensated secondary sides each having a secondary inductivity.
First claim
Opening claim text (preview).
What is claimed is: 1. A circuit for inductively transferring electrical energy from a primary side to a secondary side, comprising a primary-sided autoresonant power oscillator compensated in parallel having a primary inductivity ( 205 ) and a plurality of serially compensated secondary sides each having a secondary inductivity ( 225 , 235 , 245 ), wherein the circuit is designed to place an operating point of each recipient on the secondary side in a region of a constant voltage transfer function at the resonance frequency, so that a coupling factor between the secondary-sided recipient and the primary side is low. 2. The circuit according to claim 1 , wherein the primary-sided autoresonant power oscillator compensated in parallel is an autoresonant Royer oscillator. 3. The circuit according to claim 1 , wherein the serially compensated secondary sides each have a rectifier. 4. The circuit according to claim 1 , wherein the primary side and the secondary side are tuned to a resonance frequency that can be predetermined. 5. The circuit according to claim 1 , wherein the winding number of the secondary inductivities ( 225 , 235 , 245 ) can be varied dependent on a power to be evoked. 6. A circuit for inductively transferring electrical energy from a primary side to a secondary side, comprising a primary-sided autoresonant power oscillator compensated in parallel having a primary inductivity ( 205 ) and a plurality of serially compensated secondary sides each having a secondary inductivity ( 225 , 235 , 245 ), wherein the primary-sided autoresonant power oscillator and the secondary sides are designed in such a way that the averaged electrical energy, which all secondary sides extract, is less than or equal to the energy available on the primary side, and the operating point of all secondary sides can be found condensed in the range R 2 >R 2 , c, wherein the circuit is designed to place the operating point of each recipient on the secondary side in a region of a constant voltage transfer function at the resonance frequency, so that a coupling factor between the secondary-sided recipient and the primary side is low.
