Wireless charging method and system based on voltage regulation control

The invention provides a wireless charging method and system based on voltage regulation control, and the method comprises a wireless transmitting step of rectifying and filtering and carrying out DC/DC conversion on an alternating current connected to a power grid through a transmitting end, and using the high-frequency alternating current generated after inversion to excite a transmitting coil to generate an alternating electromagnetic field; a wireless receiving step of picking up energy from an alternating electromagnetic field generated by the transmitting coil through a receiving coil ofa receiving end by using a magnetic field coupling effect, and converting the energy into direct current through rectification and filtering to supply the direct current to a load; and a charging control step of using the transmitting end to acquire the sampling charging voltage or sampling charging current acquired by the receiving end from the load through wireless communication, and perform wireless charging control i
