The invention provides a comprehensive compensation topology capable of mutually switching constant current output and constant voltage output. A power supply module is connected with a load through an inversion module, a compensation module, a coupling module and a rectification module in sequence; the detection module is used for detecting electric quantity information of the load and feeding back the electric quantity information to the control module; the control module controls the on-off state of the compensation module according to the electric quantity information fed back by the detection module. The method has the beneficial effect that the switching between the SS compensation topology and the LCCS compensation topology is completed according to the specific condition during charging. And the battery can be ensured to be fully charged under the condition of quick charging. The wireless charging device has wide market prospects, can be used for high-power wireless charging of full-power-level electric automobiles and the like, and is high in adaptability and wide in application range.
