Abstract
This power transfer unit includes a power supply portion and a control portion, and the control portion acquires proper voltage ranges of a plurality of receivers and sets a supply voltage value in a common range among the proper voltage ranges.
Claims19
A power transfer unit comprising:
- a power supply portion;
- and
- a control portion controlling the power supply portion, wherein
- the control portion acquires proper voltage ranges of a plurality of receivers, acquires respective first supply voltage ranges corresponding to the proper voltage ranges of the plurality of receivers for respective ones of the plurality of receivers and sets a supply voltage value in a second supply voltage range which is a mutually overlapping range of the first supply voltage ranges.

A method for power transfer comprising steps of:
- acquiring proper voltage ranges of a plurality of receivers;
- acquiring respective first supply voltage ranges corresponding to the proper voltage ranges of the plurality of receivers for respective ones of the plurality of receivers;
- and
- setting a supply voltage value in a second supply voltage range which is a mutually overlapping range of the first supply voltage ranges.
1 more element
A receiver comprising:
- a communication portion sending information of proper voltage ranges;
- and
- a control portion sending the information of the proper voltage ranges through the communication portion to an external power transfer unit that acquires respective first supply voltage ranges corresponding to the proper voltage ranges of the plurality of receivers for respective ones of the plurality of receivers from the plurality of receivers and sets a supply voltage value in a second supply voltage range which is a mutually overlapping range of the first supply voltage ranges, wherein
- the control portion sends received voltage value information to the external power transfer unit through the communication portion, and disconnects a load when the receiver receives a signal, purporting that power receiving is to be stopped, transmitted from the external power transfer unit to the receiver, of which the first supply voltage range is outside the second supply voltage range of the plurality of receivers.
