双模式可调的无线电能传输

无线电能传输是一种利用近场感应将能量传送的技术。电感耦合型无线电能传输存在一些关键问题有待解决，如：转化效率低，充电过程中产生环境电磁污染等缺点。本论文探索了方波触发下输电转化效率随频率和占空比的变化规律，设计出可调频率、可调占空比的磁共振式无线充电装置，该装置具有电能转化效率最高模式和充电输出功率最大模式双重功能。

Dual-mode adjustable wireless power transmission

Wireless power transfer is a kind of technique of energy transfer, using near-field induction. Magnetic field coupling type wireless power transfer has a number of key issues to be resolved, such as, low transmission efficiency, environmental electromagnetic pollution generated during charging, etc. In this paper, we investigated the conversion efficiency of wireless power transmission changing with frequency and duty ratio under the square wave triggered, and then designed the magnetic resonance wireless charging equipment with an adjustable frequency and an adjustable duty ratio. The equipment has demonstrated two functions, i.e., the highest energy conversion efficiency mode and the charging maximum output power mode.
