RECEIVER AND TRANSMITTER OF WIRELESS ENERGY WHICH PERFORM A RESONANCE FREQUENCY TUNING WITHOUT DIRECTLY ADJUSTING AN INDUCTANCE OR A CAPACITANCE AND A SYSTEM AND METHOD FOR TRANSMITTING WIRELESS ENERGY INCLUDING THE SAME

摘要

PURPOSE: A receiver and transmitter for wireless energy and a system and method for transmitting wireless energy including the same are provided to wirelessly transmit energy through a resonance tuning.;CONSTITUTION: A quadrature oscillator(600) includes a first oscillator(605a) and a second oscillator(605b). The first oscillator outputs an I-phase signal. The second oscillator outputs a Q-phase signal which is a right-angled phase signal which has a phase difference of 90 degree with the I-phase signal. The first oscillator or the second oscillator includes resonators(610a,610b) or current varying blocks(640a,640b). The resonator includes inductors(L1-L4) or capacitors(C1-C4). The current varying block is connected to the inductor and changes a flowing current amount.;COPYRIGHT KIPO 2013;[Reference numerals] (640a,640b) Current variable block
