Problems solved by technology
Once the distance between the smart terminal and the launch base increases or the alignment is not accurate, wireless charging cannot be carried out smoothly
The system using the high-frequency wireless charging standard Airfuel Alliance, although the charging distance and the degree of freedom on the plane have been increased by increasing the operating frequency, its technology is still based on the single-directional magnetic field generated by the transmitting coil to charge the smart terminal. Therefore, there are still many requirements for the posture of the smart terminal, which greatly limits the interaction between the smart terminal user and the smart terminal during wireless charging, and limits the range of freedom of the smart terminal for wireless charging, and the user experience is not good.

The present invention relates to a wireless charging transmitting end system and a control method, the system includes at least two transmitting coils, at least two transmitting circuit units, a detection circuit, a communication module and a controller, each transmitting circuit unit is electrically connected to each transmitting coil The detection circuit is electrically connected to each transmitting circuit unit, the detection circuit and the communication module are used to obtain the coupling relationship between each transmitting coil and the receiving coil, and the controller communicates with the detection circuit, each transmitting circuit unit and The modules are electrically connected, and the controller controls the output current of each transmitting circuit unit according to the acquired coupling relationship, so as to control the current parameters of each transmitting coil. Therefore, the controller provides appropriate current amplitude and current phase for each transmitting coil by controlling the multi-channel transmitting circuit unit, so as to realize the control of the superimposed magnetic field generated by the current on the multiple transmitting coils, and then control the superimposed magnetic field on the receiving end device through the superimposed magnetic field. Charging, improving the efficiency of wireless power transmission.
Description
technical field [0001] The present invention relates to the field of wireless charging, in particular to a wireless charging transmitter system and a control method. Background technique [0002] With the development of smart terminals, wireless charging has gradually become a standard function of high-end smart terminals. Since energy is transmitted between the charger and the smart terminal using a magnetic field, there is no need for wires to connect the two. Both the charger and the smart terminal can have no exposed conductive contacts, and wireless charging can achieve relatively long-distance wireless energy conversion. , making the charging of smart terminals more free, therefore, wireless charging technology is more and more widely used. [0003] However, in the current traditional technology, for the wireless charging system of smart terminals, the wireless charging transmitter is mostly based on the charging base. The Qi standard-based wireless charging base con...
