WIRELESS POWER TRANSFER APPARATUS ADJUSTING GAIN OF LC RESONANT GENERATOR USING FIXED FREQUENCY AND METHOD FOR ADJUSTING GAIN OF LC RESONANT GENERATOR

摘要

The present specification provides a wireless power transfer apparatus which stably adjusts the transfer gain of the wireless power transfer apparatus by adjusting transfer gain by fixing the driving frequency of an inverter driving signal and generating an inverter driving signal of removed pulse, and a wireless power transfer method. For this, a wireless power transfer apparatus according to one embodiment includes multiple power translators which form wireless power signals which have different frequencies and transfer wireless power to a wireless power apparatus. The wireless power apparatus includes multiple wireless power signals which have different frequencies to wireless power receivers, respectively.
