Classification: CPC G | IPC G

Claim 9:
10. A control method by one or more hardware processors when executing processor-executable instructions stored in one or more memories in a source device that is connected to a sink device to supply power to the sink device, the method comprising:
performing negotiation with the sink device on the basis of a predetermined power standard;
performing control of supplying power to the sink device on the basis of first power information determined by the negotiation;
detecting power required by the sink device;
receiving an input of the first power information, wherein the first power information has been determined by the negotiation, and the first power information includes a voltage value and a current value of power;
receiving an input of a second power information, wherein the second power information includes a voltage value and a current value of power detected;
generating a third power information, wherein the third power information includes a voltage value and a current value on the basis of both the inputs of the first power information and the second power information and on the basis of the predetermined power standard;
performing negotiation with the sink device again on the basis of the third power information generated; and
when a current value of the second power information gets greater than a set threshold value while a power determined being supplied to the sink device as a result of the negotiation, changing the third power information by setting the current value of the first power information determined by the negotiation to be lowered by a predetermined current value in the third power information, and performing negotiation with the sink device again on the basis of the third power information changed.
