Abstract

The present disclosure provides an inductive power supply (1, 1a, 1b) and an object detection method thereof. A resonant signal is generated when the resonant capacitor (30, 30a) resonates with the power supply coil (20). A voltage detector (32) receives the resonant signal and converts it into a detection signal. A processor (4) obtains a resonant cycle of the resonant signal according to the detection signal. After the driving unit (31, 31a) drives the power supply coil (20), the resonant capacitor (30, 30a) resonates with the power supply coil (20), and a timer of the processor (4) starts timing. When the resonant cycle exceeds a cycle threshold, the timer stops timing. The processor (4) calculates and obtains a measurement of time length according to an interval between the start time and the stop time of the timer. When the measurement of time length is less than a preset time length, the processor (4) determines that there is an object within the power transmission range of the power supply module (2).
