開示の分野
本開示は無線充電コイルおよびその製造方法に関する。より特定的には、本開示はバイファイラ平行巻き(bifilar parallel wound)直列接続無線充電コイルに関する。
無線電力伝送は、電磁誘導(誘導電力)および/または共鳴周波数法によるベースステーション(電力を伝送)からモバイル装置(電力を消費)への電力の伝送である。無線電力伝送は、モバイル装置、特にスマートフォンにおいて、ますます普及が進んでいる。誘導充電技術の普及した標準規格として、ワイヤレスパワーコンソーシアムによって開発されたQiインターフェイス標準規格があり、これは電子装置間で電力の無線伝送を可能にするいくつかのプロトコルを有する。他の標準規格が無線で装置を充電するために電磁誘導または共鳴周波数を利用することもある。モバイル装置(または任意のその他の電子装置)はQiに準拠させるために所定の要求および性能基準を充足しなければならない。
本開示は無線充電コイルおよびその製造方法に関する。より特定的には、本開示は平面バイファイラ平行巻き直列接続無線充電コイルに関する。そのコイルは、従来の無線充電コイルよりも、より薄い厚み(たとえば、低プロファイル)、高められた密度(たとえば、高い充填度(fill factor))およびより高い効率(たとえば、より低い抵抗値)を有する。
図面の簡単な説明
開示の前述の特徴は、添付の図面に関連する以下の詳細な説明から明らかになるであろう。
本開示は無線充電コイルおよびその製造方法に関する。図1−7に関連して以下により詳細に述べるように、打ち抜かれた金属無線充電コイルは、バイファイラの形式で接続された一連の平行トレース(parallel traces)を備える。言い換えると、無線充電コイルは、第1および第2のコイルが平行電流を有するように、平行かつ近接し直列接続された第1および第2のコイルを含む。第1および第2のコイルは、性能要求(たとえば、電気的要求、電力要求など)を満たすために、積み重ねられまたは平面に配置され得、直列および/または並列接続され得る。無線充電コイルは、任意の電池駆動装置、特にモバイル装置(たとえば、スマートフォン、タブレット、腕時計、など)で使用することができる。無線充電コイルはQiに準拠するように作ることができるが、任意の無線伝送プロトコルに対応するよう調整し得る。銅のような導電性材料をより多く有する無線充電コイルは、コイルの厚みを変化させる(たとえば、増加させる)ことで与えられたスペースに配置することが可能であり、これはエネルギーの利用可能性を増加させる。他の無線充電コイルと比較して、ここに記載される無線充電コイルは、増大した磁気結合効果(たとえば、磁場強度)を示し、そしてそれにより高効率でエネルギーを伝送する。
