METHOD AND SYSTEM FOR WIRELESS ELECTRIC ENERGY TRANSMISSION

摘要

A method and system for wireless electric energy transmission. The method comprises: a wireless electric energy receiver converts by means of magnetic field coupling magnetic energy received from a wireless electric energy transmitter into a high frequency alternating current (S101); the wireless electric energy receiver converts the high frequency alternating current into a direct current of a sinusoidal unidirectional pulse voltage (S102); and, the wireless electric energy receiver transmits the direct current of the sinusoidal unidirectional pulse voltage to an electric appliance load (S103). The system comprises: the wireless electric energy receiver. The wireless electric energy receiver comprises: a receiving coil (401) used for converting by means of magnetic field coupling the magnetic energy received from the wireless electric energy transmitter into the high frequency alternating current; a rectifier filter circuit (401) used for converting the high frequency alternating current into the direct current of the sinusoidal unidirectional pulse voltage; and a power supply bus interface (403) used for transmitting the direct current of the sinusoidal unidirectional pulse voltage to the electric appliance load. The method and system for wireless electric energy transmission allow for implementation of universality of the wireless electric energy receiver on different kitchen electric appliances, thus achieving the goal of reduced design costs.
