Abstract

In a case that the at least one transmission antenna is transmitting a high-frequency power to at least a first wireless power reception apparatus and it is detected that at least a second wireless power reception apparatus is newly electromagnetically coupled with at least one transmission antenna, a wireless power transmission apparatus changes one of a frequency or a amplitude of the high-frequency power depending on a voltage value received from each of at least the first and second wireless power reception apparatuses, to regulate the voltage value of each power reception coil included in each of at least the first and second wireless power reception apparatuses to be equal to or lower than an upper limit value of the voltage value, circuit elements included in each of the first and second wireless power reception apparatuses being durable for the upper limit value.
