1. A method of detecting a transmit characteristic in a wireless power transmission device comprising a series element electrically coupled to a transmit coil, comprising:

  • determining real and imaginary components of a first voltage at a first terminal of the series element;

    determining real and imaginary components of a second voltage at a second terminal of the series element;

    determining real and imaginary components of a current through the series element, based on the measured first and second voltages;

    determining a transmit characteristic based on the measured voltages and determined current; and

    adjusting a characteristic of a wireless power transmission based on the calculated transmit characteristic.
