Abstract

The invention discloses a half-bridge resonant wireless energy transmission system and relates to wireless energy transmission. The half-bridge resonant wireless energy transmission system is providedwith a DC power supply, a BUCK circuit, a half-bridge inverter circuit, a first resonator, a second resonator and an auxiliary circuit. A control method comprises the following steps of achieving adjustment of output power and achieving maintenance of resonant states of the system. Wireless transmission of electric energy is carried out through an inductive coupling mode; maintenance of the resonant states of the system under different power conditions is achieved through adding the BUCK circuit to a preceding stage of the half-bridge inverter circuit; and high-efficiency electric energy transmission is achieved.

Description

technical field [0001] The present invention relates to wireless energy transmission, in particular to a half-bridge resonant wireless energy transmission system. Background technique [0002] Wireless energy transfer is a technology that transfers electrical energy to corresponding devices in a non-physical connection. There are mainly four basic methods: one is the electromagnetic induction coupling method of the loosely coupled transformer model; the other is the magnetic resonance method; the third is the laser and microwave radiation method; the fourth is the electric field coupling method. Among them, the wireless power transmission of the electromagnetic induction coupling method regards the energy transmitting end as the primary of the transformer, and the energy receiving end as the secondary of the transformer, and uses the magnetic coupling method for wireless energy transmission, which is suitable for short-distance (centimeter-level) transmission. Has entered t...
