PROBLEM TO BE SOLVED: To provide a power supply module and a power supply method for the power supply module capable of reducing power consumption of the power supply module in the case (standby state) that the power supply module and a power reception module are not within a power supply possible region, without providing an additional apparatus.SOLUTION: A power supply module 2, which is connected to an AC power source 6 and supplies power to a power reception module 3 by using a resonant phenomenon, is activated at a power source frequency at which input impedance Zof the power supply module 2 in a standby state is higher than input impedance Zof the power reception module 3 and power supply module 2 in a power supply state. |
