精工爱普生开发成功传输效率高达约70%的非接触式电源传输模块。此模块是利用电磁感应原理,从输电端模块向受电端模块传输电能而无需通过触点。输电端模块集成了初级线圈和线圈的驱动电路等,充电端模块则集成了次级线圈和二极管整流器、滤波电容器。此项技术将应用于个人数字助理(PDA)和手机等的蓄电池充电及工业用传感器非接触式供电等领域。
Seiko Epson develops non-contact power transmission modules that deliver transmission efficiencies up to approximately 70%. This module is based on the principle of electromagnetic induction, transmission from the power module to the power receiver module without passing through the contacts. The transmission terminal module integrates the driving circuit of the primary coil and the coil, and the charging terminal module integrates the secondary coil, the diode rectifier and the filter capacitor. The technology will be used in personal digital assistants (PDAs) and cell phones and other battery charging and industrial sensors contactless power supply and other fields.
