Abstract
Description
また、上記ドライブ動作はパワー素子Q1のスイッチングスピードを遅くする要因にもなる。そのため、パワー素子Q1のスイッチング損失の増加に繋がっている。よって、高周波電源装置としての消費電力が大きくなり、電力変換効率の低下の原因となっているという課題がある。
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。また、Cgs及びCgdはパワー素子Q1の寄生容量であり、Z1は高周波パルスドライブ回路1とパワー素子Q1のG端子間の信号線(ワイヤ、基板上パターンなど)のインピーダンスである。
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。
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、パワー素子Q1の駆動周波数は共振型高周波電源装置の動作周波数となり、可変型パルス信号発生回路2内部のオシレータ回路の設定により決まる。
