Abstract
A wireless power transmission device includes: a wireless power transmission unit, a power transmission circuit, a wireless communication unit, an interruption circuit, a communication circuit, and a control circuit. The power transmission circuit is connected to the wireless power transmission unit and wirelessly transmits power through the wireless power transmission unit to another party's device. The interruption circuit is connected to the wireless communication unit. The communication circuit is connected through the interruption circuit to the wireless communication unit and communicates with the other party's device via the wireless communication unit. The control circuit is connected to the power transmission circuit and the interruption circuit and, when the power is transmitted, controls the interruption circuit to interrupt between the wireless communication unit and the communication circuit on the basis of a power level transmitted by the power transmission circuit.
