Wireless power transmission system communication protocol
A control method for an inductive power supply (IPS), according to one embodiment of the present invention, can comprise the steps of: applying a ping for sensing an object; measuring a coil current; sensing the object on the basis of the coil current measurement result; transmitting, to the object, the minimum power for waking up a communication unit of the object, wherein the communication unit performs communication by using an out-of band communication protocol; receiving, from the object, pairing information through the out-of band communication protocol so as to perform pairing with the object; and transmitting main power to the paired object.
