Resonance terminal device for resonant wireless power reception system

摘要

A shunt capacitor is connected to a wireless charging resonator to prevent harmonics emitted from a power amplifier from radiating to the outside, and at least one circuit having a high impedance relative to a Near Field Wireless Communication (NFC) frequency band is formed at a front side or a rear side of the shunt capacitor for solving the problems of radiating noise components due to wireless charging and of lowering an NFC signal and a power transmission intensity due to a concurrent interference between a wireless charging resonator and an NFC antenna.

1. A resonant wireless power reception apparatus, comprising:
a Near Field wireless Communication (NFC) antenna for performing an NFC function through an NFC frequency band; and a resonator for receiving a resonant wireless power using a resonance frequency different from the NFC frequency band, wherein the resonator is installed adjacent to the NFC antenna; a shunt capacitor connected to the resonator; and a high impedance circuit for filtering a signal having the NFC frequency band provided from the NFC antenna, wherein the high impedance circuit is connected to the shunt capacitor.
