Abstract：
The invention provides a wireless energy transmission system and method, and the system is used for providing energy for a load, and comprises an emitter, a coupling coil, a rectifier bridge, and a voltage stabilization output unit which are in cascade connection. The voltage stabilization output unit is used for increasing or decreasing the value of the actual load to be equal to the value of theoptimal load when the value of the actual load is smaller than or larger than the value of the optimal load, and converting the output voltage of the rectifier bridge into a target direct-current output voltage; wherein the optimal load is a load enabling the coupling efficiency of the coupling coil to be optimal. The value of the actual load is adjusted to the value of the optimal load through the voltage stabilization output unit, the coupling efficiency of the coupling coil is improved, and therefore the energy transmission efficiency is improved.
