WIRELESS CHARGING METHOD AND SYSTEM USING RADIO FREQUENCY

摘要

PURPOSE: A wireless charging method using a microwave and a system thereof are provided to enable a power transfer station to use inexpensive night electricity by storing DC power. CONSTITUTION: A terminal(10) comprises a switch(11), a resonator(12), and a power booster(13). The switch includes an antenna for receiving a microwave of a wireless LAN(1). The switch has a path converting function by distinguishing a wireless LAN signal from a charging signal. The resonator extracts a DC component by varying matching according to a specific frequency. The power booster boosts the extracted DC to the main power of a terminal. Output of the booster is used as a charging voltage of the terminal.
