Wireless charging control method and wireless charging system

The invention provides a wireless charging control method and a wireless charging system. The control method comprises a wireless transmitting step, a wireless receiving step and a charging control step, and is characterized in that an alternating current connected to a power grid is rectified and filtered through a transmitting end, and a high-frequency alternating current is generated through aninversion link to excite a transmitting coil to generate an alternating electromagnetic field; a receiving coil picks up energy from an alternating electromagnetic field generated by the transmittingcoil by utilizing a magnetic field coupling effect, and the energy is converted into the direct current through rectification and filtering to be supplied to a load after being boosted or deboosted by the high-frequency transformer; the transmitting end performs wireless charging control through a strategy of combining a double hysteresis interval with frequency adjustment and duty ratio or phaseshift adjustment, wherein
