    • An inductively powered toy vehicle and an associated track with inductive charging segment. The vehicle may include a secondary coil, a drive motor, an electrical power storage device connected between said secondary coil and said drive motor, and a wireless communications unit. The charging segment may include a primary coil, a sense circuit operable to detect the presence of the vehicle based on a change in the detected impedance of the primary coil, and a power control unit operable to provide a time-varying current to the primary coil when the vehicle traverses the charging segment. The primary coil is positioned within the race track adjacent the track upper surface. The vehicle drive motor may be operable at first and second speed settings, and a remote control device can provide operating instructions to the vehicle wireless communications unit.

    • A power supply to provide electrical power to one or more loads. The power supply may include a resonant air core transformer to provide an adjustable and adaptable source of power to electronic devices. The power supply may include isolated primary-side circuitry and secondary-side circuitry. The primary-side circuitry may include control circuitry that, among other things, provides drive waveforms for the primary-side switching circuitry. In embodiments configured to produce AC output, the secondary-side circuitry may also include switching circuitry. The primary-side control circuitry may provide drive waveforms for the secondary-side switching circuitry. The secondary-side circuitry may include measurement circuitry that measures the current and/or voltage of the output and provides those measurements to the control circuitry through isolation circuitry. The control circuitry may adjust the drive waveforms for the primary-side and/or secondary-side switching circuitry as a function of the measured values.
