【選択図】図1
Description
(1)無接点感知式電力伝送商品の電力発射端は、コイルを共振回路に組み合わせてエネルギーを発射するもので、発射エネルギーの大きさは通電後変化させることができず、需要端の電子装置が必要パワーを変化させた時であっても、発射端はパワーを変化させられず、パワー不足或いはパワーの浪費等の欠点が存在する。
(2)受信端二次側の共振コンデンサと受信コイルとは並列連結し、無負荷作業の状態において、継続してパワーを消耗するため、エネルギー浪費という欠点が存在する。
(3)コイルは単一芯を用いた絶縁性エナメル銅線を巻き付けて形成されるが、コードレス供電作動時、発熱すると、伝送効率を悪くし、パワーを低下させる。
(4)受信端に安全回路が配置しておらず、ショートや電流過大が発生した場合、電子装置の損傷を引き起こす。
(1)コードレス供充電受信装置2の検知保護モジュール24が電源底部1によって供給された電源状況、即ち、共振部品の品質、二次側受信コイルの相対位置、二次側受信負荷状態等の要素を検知する。並びに、第二マイクロプロセッサ25、信号生成回路26、第二共振回路22、及び第二コイル21によって信号を電源底部1に伝送し、電源底部1は自動的に出力パワーを調整するため、エネルギー伝送の損失を低下させ、受信コイルの有効範囲を更に拡大し、コードレス供充電受信装置2内部部品が受け取る余分なパワーの変換も大幅に低下させる。
(2)電源底部1のパワー切換駆動回路13にフルハーフブリッジ駆動回路131と並列連結した第一モスフェットアレイ132及び第二モスフェットアレイ133を用い、継続的に供電し操作する状況下でフルハーフブリッジ駆動回路131はスピーディにパワー出力を切り換え、更にフルハーフブリッジ駆動回路131は、無作業時での第一モスフェットアレイ132と第二モスフェットアレイ133の通路の漏電を遮断し、回路静止時の消耗を最低にする。
(3)第一コイル15と第二コイル21は、複数のエナメル線をより合わせた後に粘性絶縁材質を粘着させた線材を巻き付けて単層の扁平矩形形状を形成することにより、第一コイル15及び第二コイル21は高周波数下で低抵抗を備えるだけでなく、十分なインダクタンスも備えたものとなる。
(4)コードレス供充電受信装置2において第二コイル21に第二共振回路22の共振コンデンサを連結することにより、共振が無負荷時の消耗をゼロとし、重負荷時に優位的に大きなパワーが得られる。
(5)コードレス供充電受信装置2の検知保護モジュール24において整流フィルタ回路23とレギュレータ241の間に遮断保護回路245を配置し、レギュレータ241と昇降圧型レギュレータ243を電流検知保護回路244に電気的に接続させ、電流検知保護回路244内には自動回復可能な過電流リセットヒューズを使用することにより、電流過大時の遮断保護回路245への供電を遮断し、電流検知保護回路244の過電流リセットヒューズによって自動遮断及び保護を行う二重保護効果を備え、火事、損傷を防止する。
