先进的无线电源部件使设计充电器比以往任何时候都更容易
有多少手机、音乐播放器和其他便携设备,我们扔到垃圾桶,因为片状电源连接器?看来,需要充电我们的设备,使最终的电源连接器将被强调的点有间歇性连接或开路。鉴于修理费用,它不支付修复它(和好运找到有人愿意处理维修)。一个答案的势头是避开连接器完全支持无线充电。
虽然一个新奇的第一,无线充电到先进的制造商提供的块和/或整个解决方案,可以很容易地纳入您的设计。不再有一个需要手动风定制线圈垫或被众多手工制作任务约束。
本文将研究无线充电技术的状态以及现成的部件和解决方案。这些资源使它更快速,更容易添加无线充电到您的设计没有昂贵的迭代和手工制作步骤。所有的配件,说明书,教程,和开发包,可以参考这里Digi-Key的网站上找到。
It’s a transformer
Basically, wireless power transfer is a coil next to a coil, or in other words, a transformer. In this case, the transformer is air-coupled rather than wound around a common ferrite core. In all cases, as one side oscillates, its field radiates outward until it slices through another coil which recovers power in AC form.
PCB traces can be used as a coil in some cases. As with transformers, voltage and current ratios in PCB Traces depend on the number of turns in primary and secondary coils. As a result, size and trace density may limit the number of turns possible on a PCB and the maximum amount of current a trace can carry. This makes real wound coils more desirable and effective.
