METHODS AND APPARATUS FOR TUNING AND CONTROLLING DOUBLE COUPLE INDUCTIVE POWER TRANSFER SYSTEMS |
摘要 |
An apparatus for transmitting charging power wirelessly to a vehicle is provided. The apparatus comprises a first coupler having a first reactance at an operating frequency and configured to wirelessly receive power from a power source, the first coupler wound on a ferromagnetic core. The apparatus comprises a first capacitor having a second reactance at the operating frequency and electrically connected in series with the first coupler, the second reactance having a magnitude equal to a magnitude of the first reactance. The apparatus comprises a second capacitor electrically connected in parallel across the first coupler and the first capacitor. The apparatus comprises a first base coupler configured to be electrically connected in parallel across the second capacitor via a first switch. A magnitude of a peak voltage across the second capacitor is proportional to a magnitude of a peak voltage induced in the first coupler at the operating frequency. |
