無線式手機電能對充技術之探討

PHONE-TO-PHONE WIRELESS CHARGING SOLUTION

本研究提出一種嶄新的無線式手機電能對充技術。該想法係以振盪器將供電端手機之直流電源轉換成交流電源，透過非接觸式感應原理使交流電源經供電端線圈耦合至受電端線圈，再經過交直流轉換裝置後使受電端手機達到充電的目的。本創新技術之目的是為解決手機待機缺電的情況，當四周環境無充電裝置可補充電量時，急用者可藉其它具備相同功能的手機，利用此技術進行手機對手機無線式電量轉移來達成電量補充，供緊急救援用途。本創作由於不須導線，可提昇便利性。

This paper proposes a new idea for a wireless charging method betweentwo mobile phones. It adopts an oscillator in the supplying sideconverting its DC power from the embedded battery to AC power; acontactless interface consists of a coil induces magnetic effect in the acceptingside which is also equipped with a contactless interface with a coilto induce AC power from the supplying side. The AC power is then regulatedand converted to DC power, after passing through a voltage booster,to charge the embedded battery in the accepting side. The purpose is toextend the durability of the mobile phone’s battery by conveniently acceptingextra power from other mobile phones around without resorting towired connections. Convenience is significantly enhanced when comparedwith other the existing inventions, which rely solely on the wired connections.
