The embodiment of the invention provides a control method for wireless charging, a wireless charging device and a wireless charging system. The control method comprises the following steps: controlling a first power converter at a secondary side to charge a rechargeable load with a first set current; receiving a sensing signal representative of an output current of a second power converter at the primary side; and in response to the output current reaching or exceeding the threshold current, controlling the first power converter to charge the rechargeable load with a second set current less than the first set current. According to the scheme, power derating of the wireless charging system can be achieved, and it is ensured that components on the primary side of the system work within a safe range.

    本公开的实施例提供了一种用于无线充电的控制方法、无线充电装置以及无线充电系统。该控制方法包括:控制次级侧处的第一功率变流器以第一设定电流向可充电负载充电;接收表示初级侧处的第二功率变流器的输出电流的感测信号;以及响应于输出电流达到或超过阈值电流,控制第一功率变流器以小于第一设定电流的第二设定电流向可充电负载充电。本公开的方案可以实现无线充电系统的功率降额而且确保系统初级侧的部件工作在安全范围内。
