  • Power input circuits
    Patent number: 9748793
    Abstract: A power input circuit. A wireless power receiver receives power from a wireless power transmitter. A charging circuit is coupled to the battery. A first switch is controlled by a first control signal. A second switch is controlled by the first control signal. A third switch is coupled between the battery and the voltage input terminal and controlled by a second control signal. A fourth switch is coupled between the voltage input terminal and the charging circuit and controlled by a third control signal. A fifth switch is coupled between the wireless power receiver and the charging circuit and controlled by a fourth control signal. When the wireless power receiver receives power, the third switch and the fifth switch are closed to transmit the received power to the charging circuit for charging the battery, and the computer device is powered by the battery.
