Abstract
A wireless power transmission and charging system, and a power control method of the wireless power transmission and charging system are provided. The power control method may include generating charging power using the power amplifier. The charging power may be used to charge a target device. The charging power may be transmitted to the target device. The voltage supplied to the power amplifier may be adjusted based on a detected change in the current input to the power amplifier, a detected change in the temperature of the source device, a detected change in the amount of the power received to the target device, or a detected change in the temperature of the target device.
