为摆脱掉移动电源的数据线束缚,提出了一种基于E类功放的非接触式移动电源供电系统.将移动电源的电压升压后供给E类功放,可分离变压器根据高频电磁耦合原理将能量大范围扩散,同频振动的接收端进行磁电转换,电能调整后给电子设备充电. E类拓扑能够实现能量的最大传输,可以实现高效率的非接触式移动电源供电. 利用线圈自身的分布电容构成自谐振增加2个共振环节实现高频电磁耦合,用户不需要使电子设备与充电装置完全正对. 对两者的工作原理进行分析,制作一个移动电源的供电系统样机,通过实验结果验证该系统的设计.

A contactless mobile power supply system based on class E-power amplifier is proposed to get rid of data cable of mobile power.Traditional wireless charger uses electromagnetic induction principle,implements QI standard,with short distance of wireless energy transmission and low efficiency.The design boosts mobile power voltage for class E-power amplifier, then the detachable transformer spreads energy far and wide according to magnetic resonance principle, the receiving end of the same frequency vibration transforms magnetic and electric,finally the electricity charges electronic devices.Class E-topology can achieve maximum transmission of energy and high-efficiency supply of contactless mobile power.Adding 2 resonance link to achieve magnetic resonance by using distributed capacitance of the coil itself,users do not need to make the electronic device completely right to the charging device.Analyzing the two work principles, we make a prototype of the mobile power supply system,and verify the design by experiment results.
