Abstract
Description
実施の形態1.
図1はこの発明の実施の形態1に係る共振型高周波電源装置の構成を示す図である。なお図1では、パワー素子Q1がシングル構成の場合の回路を示している。
共振型高周波電源装置は、図1に示すように、パワー素子Q1、共振回路素子(コンデンサC1,C2及びインダクタL2)、インダクタL1、高周波パルスドライブ回路1、可変型パルス信号発生回路2及びバイアス用電源回路3から構成されている。
なお、共振型送信アンテナ(電力伝送用送信アンテナ)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)。この共振型送信アンテナ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。
図2はコイル21の磁路長(L値)を手動又は自動で可変するタイプの可変型のインダクタL2を示している。なお図2において、コイル21のターン数は同じである。図2(a),(b)は、磁路長調整機構(手動、又はモータにより自動で可変させる機構)22によりコイル21の磁路長(L値)を可変する場合を示し、図2(c)は、L値制御電源23により電磁誘導でL値を可変する場合を示している。
まず、入力の直流電圧VinはインダクタL1を通してパワー素子Q1のD端子に印加される。そして、パワー素子Q1は、その電圧をON/OFFのスイッチング動作により正電圧の交流状電圧へ変換する。この変換動作のときに、インダクタL1は一時的にエネルギーを保持する働きをして、直流を交流へ電力変換する手助けを行う。
また、可変型のインダクタL2のL値を調整することで、図4に示すように、出力電圧Voutの電圧振幅を任意の値に設定することができる。
