自动谐振的电动汽车无线充电装置

目前电动汽车充电方式多通过有线充电方式,极其限制电动汽车的普及.而无线充电技术多以电路较简单的较成熟的感应式无线充电技术为主,电磁感应的磁场发散性较强,对距离及放电受电线圈要求位置要求较高.现电动汽车充电装置的磁耦合共振无线传输系统多针对固定汽车型号.本文主要研究通过接收次级回路的参数,从而控制主回路电容调制,以自动谐...

Automatic Resonance Electric Vehicle Wireless Charging Device

At present,most electric vehicle charging methods are wired charging methods,which extremely restricts the popularization of electric vehicles.The wireless charging technology is mostly based on the more mature inductive wireless charging technology with simpler circuits.The magnetic field of electromagnetic induction has strong divergence,and it has higher requirements on the distance and the position of the discharge power receiving coil.The current magnetic coupling resonance wireless transmission system of electric vehicle charging devices is mostly aimed at fixed vehicle models.This paper mainly studies the control of the capacitance modulation of the main circuit by receiving the parameters of the secondary circuit,and the automatic resonance magnetic coupling resonance wireless transmission system to realize the charging of different receiving circuits,so as to meet the charging compatibility of different types of electric vehicles.
