Abstract
Description
本発明の目的は、誘導電力伝達のための改善された電力供給回路、装置、もしくは方法、または道路給電式電動車両システムもしくはそのようなシステムと共に使用するための車両もしくは道路を提供することである。あるいは、目的は、従前の提案に対して有用な代替物を提供することである。
誘導的に電力を受電するためのピックアップコイルと、
前記受電した電力からのエネルギーを貯蔵するためのストレージキャパシタと、
ストレージキャパシタからの電気エネルギーを磁束結合装置に供給するためのインバータと、を備え、
磁束結合装置によって供給される負荷に対する電力伝達が、前記受電した電力を超過し得る、回路、を提供する。
誘導的に電力を受電することと、
前記受電した電力からのエネルギーを貯蔵手段内に貯蔵することと、
貯蔵手段からの電気エネルギーを磁束結合装置に供給し、負荷に対して電力を誘導的に提供することと、を含む、誘導電力伝達の方法、を提供する。
誘導的に電力を受電するための手段と、
前記受電した電力からのエネルギーを貯蔵するための貯蔵手段と、
貯蔵手段からの電気エネルギーを磁束結合装置に供給するための供給手段と、を備える、回路、を提供する。
すぐ前の文による複数の回路と、
ピックアップによって必要とされる電力に応じて、磁束結合デバイスのうちの1つまたは2つ以上に選択的に電力を供給するための制御手段と、を備えている、システム、を広く提供する。
複数の誘導電力伝送モジュールを有する道路を備え、各モジュールが先行する文のうちのいずれか1つによる回路を含むか、またはそれと関連付けられている、道路給電式電動車両システム、を提供する。
誘導的に電力を受電することと、
前記受電した電力からのエネルギーを貯蔵手段内に貯蔵することと、
貯蔵手段からの電気エネルギーを磁束結合装置に供給することと、を含む、誘導電力伝達の方法を提供する。
誘導的に電力を受電することと、
各貯蔵要素が磁束結合デバイスに関連付けられている、複数の貯蔵要素内に前記受電した電力を貯蔵することと、
磁束結合デバイスの上方を、かつ/または磁束結合デバイスの間をピックアップが移動するにつれて、貯蔵要素からの電力を磁束結合デバイスのうちの1つまたは2つ以上に選択的に供給することと、を含む、電力供給方法、を広く提供する。
Δ(1/2CV2)=1000J、よって
CVΔV=1000、ゆえにΔV=1000/CV
300V、1Fのキャパシタを有する実用的な応用では、このシナリオにおける電圧の変化ΔVは、1000/300=3.3ボルト、すなわち1%の放電になるであろうが、これは完全に実用的な結果である。
