Abstract
Description
そして、整流動作時に発生する回路の電力損失は、熱エネルギーとなって回路基板の温度上昇に繋がる。これは、回路基板の動作環境温度を上げることになり、使用部品の寿命を短くすることになる。そのため、排熱装置を備えるなどの対策が必要となり、コスト増、大型化、質量増の原因にもなっている。
実施の形態1.
図1はこの発明の実施の形態1に係る高周波電源用整流回路の構成を示す図である。
高周波電源用整流回路は、2MHz以上の高周波における交流電圧Vinの整流を行うものである。この高周波電源用整流回路は、図1に示すように、ダイオードD1、コンデンサC1,C12、インダクタL1、コンデンサC21及びインダクタL11から構成されている。
なお、共振型受信アンテナ(電力伝送用受信アンテナ)10は、LC共振特性を持つ電力伝送用の共振型アンテナである(非接触型のみに限定されない)。この共振型受信アンテナ10は、磁界共鳴型、電界共鳴型、電磁誘導型のいずれであってもよい。
まず、共振型受信アンテナ10から2MHz以上の高周波の交流電圧Vinが入力されると、インダクタL11とコンデンサC12による複合機能により、共振型受信アンテナ10の出力インピーダンスとの整合と、コンデンサC1,C12とインダクタL1による部分共振回路とのインピーダンス整合が図られる。そして、その整合状態を維持しながら、ダイオードD1により、入力された交流電圧Vinが片側電位(正電位)のリップル電圧に整流される。このとき、ダイオードD1によるスイッチング動作は、コンデンサC1,C12とインダクタL1による複合機能により部分共振スイッチング動作となり、ZVS(ゼロボルテージスイッチング)状態となる。この状態がスイッチング損失の最も少ない整流動作となる。そして、整流されたリップル電圧は、コンデンサC21により直流電圧へ平滑され出力される。
以上の一連の動作により、入力された高周波の交流電圧Vinを高い電力変換効率(90%以上)で直流電圧へ整流し出力することが可能である。
また、整流動作時に発生する回路の電力損失が少ないため、発生する熱エネルギーも少なく回路基板の温度上昇を低く抑えられることから、動作環境温度が使用部品の寿命に与える影響を少なくできる。そのため、従来の排熱装置を備えるなどの対策が不要となり、コストの削減、小型、軽量化及び低消費電力化を図ることができる。
図1〜5についても同様に共振条件可変型LC回路1を適用可能である。
図8はこの発明の実施の形態2に係る高周波電源用整流回路の構成を示す図である。図8に示す実施の形態2に係る高周波電源用整流回路は、図1に示す実施の形態1に係る高周波電源用整流回路のダイオードD1をパワー素子Q1に変更したものである。その他の構成は同様であり、同一の符号を付して異なる部分についてのみ説明を行う。
このように、ダイオードD1に代えてパワー素子Q1を用いて高周波電源用整流回路を構成するようにしても、実施の形態1と同様の効果を得ることができる。
