Output device for wireless charging

Abstract

An output device for wireless charging, relating to the field of wireless charging. The output device for wireless charging comprises an isolation transformer (12), a first numerical control switch unit (14), a wireless coil module (13), an information extraction unit (15), and a processor unit (16). The primary side of the isolation transformer is connected to a direct current input end. The first numerical control switch unit generates an alternating current on the primary side of the isolation transformer by means of connection and disconnection. The wireless coil module outputs alternating current electric energy needed for wireless charging. The information extraction unit is used for extracting current information on the isolation, filtering and regulation isolation transformer to obtain corresponding real-time information, and transmitting the real-time information to the processor unit. The processor unit obtains a control signal according to the real-time information and controls the first numerical control switch unit to work. In the output device for wireless charging, conventional modules having large volumes, high power consumption and high costs are removed, the circuit is simplified, the power loss is reduced, and the overall efficiency of the output device for wireless charging is improved; and meanwhile, costs are greatly reduced, and the product volume is reduced.
