| description | The invention discloses a wireless power supply device and a load identification method and identification device thereof, the wireless power supply device comprises an inverter circuit and a resonance circuit, the resonance circuit comprises a resonance coil, and the method comprises the following steps: controlling the inverter circuit to work at different preset frequencies; obtaining the current magnitude of the resonance coil and/or the system resonance frequency under each preset frequency; and identifying the load type on the wireless power supply device according to the current magnitude and/or the system resonant frequency. According to the load identification method, the load type is determined by acquiring the current magnitude and/or the system resonant frequency under different preset frequencies, so that heating control or wireless charging control on the load is determined according to the load type.
本发明公开了一种无线供电装置及其负载识别方法和识别装置，所述无线供电装置包括：逆变电路和谐振电路，谐振电路包括谐振线圈，所述方法包括：控制逆变电路工作于不同的预设频率；获取每个预设频率下谐振 |
