임피던스 변화검출장치
摘要：
임피던스변화검출장치를개시한다. 본실시예의일 측면에의하면, 무선으로전력을전송하는장치에있어서, 전원을제공하는전원장치와전원을인가받아자속을발생시키는공진기와상기공진기의임피던스변화여부를수신하며, 상기임피던스변화정보에따라공진기에전원을제공할지를제어하는제어부및 코일을포함하며, 상기공진기가발생시키는자속에의해상기코일에서발생하는유도전류를이용하여상기공진기의임피던스변화여부를검출하고, 상기공진기의임피던스변화여부를상기제어부로전달하는임피던스변화검출장치를포함하는것을특징으로하는무선전력전송장치를제공한다.
摘要（英）：

Disclosed is a device for detecting an impedance change. According to an embodiment of the present invention, a device for transmitting power wirelessly comprises: a power device providing the power; a resonator generating a magnetic flux by receiving the power; a control part receiving whether the impedance of the resonator changes, and controlling whether to provide the power to the resonator depending on the impedance change information; and a coil. The device for transmitting wireless power detects whether the impedance of the resonator changes by using induced current generated in the coil by the magnetic flux generated by the resonator, and includes an impedance change detection device transmitting to the control part whether the impedance of the resonator changes.
