Systems and Methods for Dynamically Tuning a Wireless Power Transfer System

DRIVE November 7, 2024

A wireless power transmission system includes a voltage regulator, an inverter, a capacitor circuit, an antenna, and a controller. The inverter receives a first alternating current (AC) signal that has a configurable frequency and produces a configurable supply voltage. The inverter produces a second AC signal based on the first AC signal and the configurable supply voltage. The second AC signal has the configurable frequency and a configurable power level that corresponds to the configurable supply voltage. The capacitor circuit includes two or more capacitors and is configured to, based on a configuration state of the bank of two or more capacitors, tune the second AC signal with the bank of two or more capacitors and thereby produce a third AC signal. The controller is configured to define the configurable frequency, define the level of the configurable supply voltage, and define the configuration state.
