  • Wireless power transmitter and method of controlling the same
    Patent number: 10218220
    Abstract: A wireless power transmitter includes a resonator configured to transmit a detection signal; a period detector configured to detect a period of oscillation of an oscillation signal caused by remnants of the detection signal; and a controller configured to determine whether an external charging object is approaching in response to a change in the period of the oscillation signal.
    Type: Grant
    Filed: October 20, 2016
    Date of Patent: February 26, 2019

  • SOLAR POWER SUPPLY APPARATUS AND METHOD OF CONTROLLING POWER SUPPLY THEREOF
    Publication number: 20140301113
    Abstract: There are provided a solar power supply apparatus switching a synchronous rectifying switch instead of a snubber switch to increase power conversion efficiency, and a method of controlling power supply thereof. The solar power supply apparatus includes a power supply unit switching power input by a photovoltaic cell to convert power, synchronously rectifying and outputting the power converted depending on the power conversion switching, and suppressing surplus power generated by the power conversion switching in a snubbing operation; and a control unit controlling the synchronous rectification operation and the snubbing operation of the power supply unit depending on a spike voltage generated by the power conversion switching.
