Abstract:
A power transmitting apparatus that wirelessly transmits power to one or more power receiving apparatuses determines whether each of the one or more power receiving apparatuses has a function for internally lowering a voltage obtained through power reception, and controls the transmitted power so that, in a case where at least one of the one or more power receiving apparatuses does not have the function, overvoltage is not applied to the power receiving apparatus that does not have the function.
