Abstract: A device for wirelessly charging a battery includes a power amplifier having a transmitter coil generating a magnetic field for wirelessly charging a battery. A low pass filter arrangement is electrically coupled to an output of the power amplifier. A band stop filter is electrically coupled to an output of the low pass filter arrangement. An output of the band stop filter is electrically coupled to a resistive load associated with the battery. The low pass filter arrangement and the band stop filter are configured to transform a load impedance associated with the transmitter coil to produce a current at the output of the power amplifier that remains substantially constant in response to changes in the load impedance.
