Beschreibung
Zusammenfassung:	The disclosure provides a wireless power supply device, which includes: a power transmission coil; a first driving unit that alternatively performs an operation of transmitting a first driving current to one end of the power transmission coil and an operation of drawing a second driving current away from one end of the power transmission coil; a second driving unit that alternatively performs an operation of transmitting the second driving current to the other end of the power transmission coil and an operation of drawing the first driving current away from the other end of the power transmission coil; a current detection unit that detects amounts of the transmitted first and second driving current to generate a first signal, and detects an amount of the drawn second driving current to generate a second signal; and a control unit that determines an operation state based on the first and second signal.
