Abstract
A wireless power transceiver includes input generator, inverter, battery, antenna, impedance matching circuit, and mode voltage changer. The input generator outputs an input voltage as a primary input voltage and a secondary input voltage in a power transmitting mode. The input generator outputs a power supply voltage as a primary input voltage and outputs a ground voltage as a secondary input voltage in a power receiving mode. The inverter outputs to the second node, an inverted version of the input voltage in the power transmitting mode, and outputs to the first node, a rectified voltage of the second node in power receiving mode. The impedance matching circuit is connected between the second node and the antenna. The mode voltage changer converts a battery voltage of the battery to output the power supply voltage in the power transmitting mode, and charges the battery with a voltage converted from the power supply voltage in the power receiving mode.
