Intermediate Resonant Circuit Based Wireless Charging Technology
Existing wireless charging technologies for electric vehicles required complex sensors, closed-loop controllers and communications facilities which resulted for bulky in size. A new wireless charging technology based on a novel reconfigurable intermediate resonant circuit is design to reduce complexity and increase efficiency and reliability. Based on a new magnetic coupling structure, the system is able to achieve wireless load-independent constant current charging and constant voltage charging without the need of communication between the receiver and the transmitter side. This new technology can stimulate the large-scale deployment of electric vehicles with wireless charging. Also, it is applicable for mobile items like electric bicycles and smart phones.
