Description
図1は、本発明の実施形態1における無線電力伝送システムの構成を示すブロック図である。
本発明の無線電力伝送システムのインダクタLsにおいて、伝送効率改善のために配線抵抗値を低減する際に、インダクタLsの配線経路の全てにおいて、配線抵抗を低減する必要はない。本発明の効果は、インダクタLsの経路の一部の配線抵抗低減によっても実現できる。
図7は、本発明の無線電力伝送システムにおけるインピーダンス整合を説明するための図である。図7では、フィードバック制御を行う機能ブロックなどは省略されている。これらの機能を実現する不図示のブロックが必要に応じて追加され得る。
伝送システム内に含まれる送電共振器と受電共振器の台数はそれぞれ1に限定されない。送電共振器群と受電共振器群の中で、電力の伝送を行う組み合わせの内の少なくとも一組の、サイズが非対称な送電共振器と受電共振器の組み合わせにおいて、上述した抵抗値低減の構成が採用されれば本発明の有用な効果は発現し得る。
送電共振器および受電共振器において、容量回路CL、Csは、チップ容量素子やセラミックコンデンサ、タンタル電解コンデンサ、アルミ電解コンデンサ、マイカコンデンサ、電気二重層コンデンサ、真空コンデンサ、半導体プロセス上で形成されるMIM構造などの集中定数回路素子で実現されてよい。また、配線に分布して発生する寄生容量の値を考慮し、上記集中定数回路素子の容量値は決定されてよい。
