WIRELESS POWER TRANSMISSION DEVICE USING FREQUENCY MULTIPLIER AND METHOD THEREOF
First Claim
1. A wireless power transmission device, comprising:
- a signal input unit configured to receive a first alternating current (AC) signal;
a frequency multiplier configured to output a second AC signal having a higher frequency than the first AC signal using harmonic components of the first AC signal; and
a power transmission unit configured to transmit power by receiving the second AC signal.

Abstract
There are provided a wireless power transmission device using a frequency multiplier and a method thereof. The wireless power transmission device using the frequency multiplier includes a signal input unit configured to receive a first alternating current (AC) signal, a frequency multiplier configured to output a second AC signal having a higher frequency than the first AC signal using harmonic components of the first AC signal, and a power transmission unit configured to transmit power by receiving the second AC signal. Accordingly, a complex structure in which an AC signal is converted into a DC signal and the DC signal is converted into the AC signal again in order to generate the AC signal for the wireless power transmission can be simplified by the frequency multiplier. Moreover, it is possible to efficiently and wirelessly transmit low power required for ambient scattered sensor nodes.
