Abstract: In one aspect, an apparatus for charging a device includes a charger and a controller. The charger includes a capacitance and has a charger input and a charger output. The charger input receives an AC input voltage waveform, and the charger output outputs an output voltage waveform and an output current waveform. The controller determines whether an amplitude of the output voltage waveform is within a voltage range. In response to determining that the amplitude of the output voltage waveform is within the voltage range, the controller directs an amplitude of the output current waveform to be substantially proportional to an amplitude of the AC input voltage waveform. In response to determining that the amplitude of the output voltage waveform is not within the voltage range, the controller increases the capacitance of the charger to adjust the amplitude of the output voltage waveform to be within the voltage range.

Abstract: Exemplary embodiments are directed to wireless power. A wireless power receiver includes a receive antenna for coupling with near field radiation in a coupling-mode region generated by a transmit antenna operating at a resonant frequency. The receive antenna generates an RF signal when coupled to the near filed radiation and a rectifier converts the RF signal to a DC input signal. A direct current (DC)-to-DC converter coupled to the DC input signal generates a DC output signal. A pulse modulator generate a pulse-width modulation signal to the DC-to-DC converter to adjust a DC impedance of the wireless power receiver by modifying a duty cycle of the pulse-width modulation signal responsive to at least one of a voltage of the DC input signal, a current of the DC input signal, a voltage of the DC output signal, and a current of the DC output signal.

Abstract: Exemplary embodiments are directed to wireless power transfer. A transmitting device or a receiving device for use in a wireless transfer system may be equipment or a household appliance. The transmitting device includes a transmit antenna to wirelessly transfer power to a receive antenna by generating a near field radiation within a coupling-mode region. An amplifier applies an RF signal to the transmit antenna. A presence detector detects a presence of a receiver device within the coupling-mode region. A controller adjusts a power output of the amplifier responsive to the presence of a receiver device. The presence detector may also detect a human presence. The power output may be adjusted at or below the regulatory level when the presence signal indicates human presence and above a regulatory level when the presence signal indicates human absence.
