Abstract
Systems, apparatuses and methods for an adaptable tuning circuit for a wireless power transfer system including an inductor and a capacitor. An input may be configured to receive alternate current (AC) power. An RC circuit may include a resistor and a supply capacitor, where a first diode is configured to be forward biased when the AC power is positive for charging the supply capacitor, and a second diode is configured to be forward biased when the AC power is negative for minimizing discharge from the supply capacitor. A tuning logic is provided for controlling power from the supply capacitor to a tuning circuit comprising a tuning capacitor and a switch arrangement, wherein the tuning circuit is configured to be parallel to the capacitor of the wireless power transfer system.
