Abstract
Included are embodiments of a wireless charging device. Some embodiments include a transmitting side resonant tank circuit that includes a transmitting side tank capacitor and a primary transmission coil. Also included is a bridge component that is coupled to the transmitting side resonant tank circuit for driving the transmitting side resonant tank circuit. The bridge component may be configured to receive a voltage from a power supply for supplying a rail of the transmitting side resonant tank circuit. A regulator circuitry may also be included, which controls the bridge component. The regulator circuitry may execute logic that controls an amount of power that is delivered to the transmitting side resonant tank circuit. Similarly, a current sensing element may be included that informs the regulator circuitry of an amount of current drawn from the power supply.
