三礼电子推出WPT系列无线充电线圈组件,符合Qi标准,适用于手机、平板电脑、dsc等便携式电子设备
现今几乎所有的电子设备,如手机,MP3和笔记本电脑等,进行充电的方式主要是有线电能传输,既一端连接交流电源,另一端连接便携式电子设备充电电池的。这种方式有很多不利的地方,首先频繁的插拔很容易损坏主板接口,另外不小心也可能带来触电的危险。
无线充电运用了一种新型的能量传输技术——无线供电技术。该技术使充电器摆脱了线路的限制,实现电器和电源完全分离。在安全性,灵活性等方面显示出比传统充电器更好的优势。在如今科学技术飞速发展的今天,无线充电显示出了广阔的发展前景。
无线供电原理及实现方式:
无线充电利用电磁波感应原理进行充电,原理类似于变压器。在发送和接收端各有一个线圈,发送端线圈连接有线电源产生电磁信号,接收端线圈感应发送端的电磁信号从而产生电流。
2007年6月麻省理工学院以Marin Soljacic为首的研究团队首次演示了利用电磁感应原理的灯泡无线供电技术,他们可以在一米距离内无线给60瓦的灯泡提供电力,电能传输效率高达75%。
研究者由此设想电源可以在这范围内为电池进行无线充电,进而推想只需要安装一个电源,即可为整个屋里的用电器供电。传输线圈的工作频率在兆赫兹范围,接收线圈在非辐射磁场内部发生谐振,以相同的频率振荡,然后有效的通过磁感应进行电能传输。
应用:
适用于手机、平板电脑、dsc等便携式电子设备的收发模块。
