WIRELESS POWER TRANSMISSION SYSTEM FOR OPTIMAL POWER TRANSMISSION, AND METHOD FOR CONTROLLING OPTIMAL RESONANCE FREQUENCY OF SAME SYSTEM

The present invention relates to a design of a wireless power transmission system and a method for controlling an optimal resonance frequency applied to the system, and provides a wireless power transmission system and a method for controlling an optimal resonance frequency applied to the system, wherein, by a method of designing a power transmission unit to match a frequency control range and by designing a quality factor (Q) of a resonance unit of a power reception unit to be low so that the difference in power reception performance is not large within the control frequency range, power can be received stably even if there is a change in resonance frequencies of a wireless power transmission system installed in a metal environment, and the system frequency can be easily and quickly controlled so as to search for and find the optimal resonance frequency.
