Description
本明細書における先行技術への言及は、そのような先行技術が公共の一般的知識の一部を形成しているとの自認を構成するものではない。
本発明の一実施形態においては、第1のスイッチング事象は、第1のスイッチ6または第2のスイッチ7をまたぐ電圧がゼロになり、あるいはゼロに近づくときである。すなわち、第1のスイッチは、第1のスイッチの電圧がゼロになり、あるいはゼロに近づくときにオンになり、第2のスイッチは、第2のスイッチの電圧がゼロになり、あるいはゼロに近づくときにオンになる。第1のスイッチ6または第2のスイッチ7の電圧は、出力インダクタ4をまたぐ電圧に依存するため、コンバータの従属変数に関係しうる。このやり方で、第1のスイッチング事象の発生がシステムにおける変化とともに変化できるため、オンに切り換わるスイッチが、システムにおける変化に適応することができる。
本発明の一実施形態においては、2つのスイッチが存在しており、第2のスイッチング事象は、他方のスイッチがオフにされた後に所定の時間間隔(α)が経過することである。すなわち、第1のスイッチ6が、第2のスイッチがオフにされた後に所定の時間間隔(α)でオフにされ、第2のスイッチ7が、第1のスイッチがオフにされた後に所定の時間間隔(α)でオフにされる。第1のスイッチまたは第2のスイッチのオフへの切り換えは、システムの従属変数に関係していない(すなわち、あらかじめ設定され、変化することがない)ため、システムのいかなる変化にもかかわりなく同じままである。さらに、スイッチは、所定の時間間隔の後で継続的にオフであるため、スイッチの周波数も、システムの従属変数に関係していない。コンバータの周波数は、下記の式によって計算することができる。
・他方のスイッチのオンへの切り換わり。
Claims (11)
- インダクタを有する共振回路を備えており、前記インダクタを通過する電流の方向が関連の第1および第2の制御スイッチの状態に依存するコンバータを制御する方法であって、各々の前記第1および第2の制御スイッチは、
a.前記コンバータの従属変数に関係したゼロ交差の発生に応じて第1の状態へと切り換わり、
b.前記コンバータの従属変数に関係しない所定の時間期間の終わりに応じて第2の状態へと切り換わり、
前記所定の時間期間は、同じ前記第1および第2の制御スイッチまたは別の前記第1および第2の制御スイッチがオフへと切り換えられた後に開始する方法。 - 前記第1の状態が、オン状態であり、前記第2の状態が、オフ状態である請求項1に記載の方法。
- 前記第1の状態が、オフ状態であり、前記第2の状態が、オン状態である請求項1に記載の方法。

- 前記コンバータの所望の動作周期は、該コンバータの無負荷時の固有共振周期と同様であるように選択される請求項4または5に記載の方法。
- 前記所定の時間期間は、実質的に固定のコンバータの周波数を決定する請求項1に記載の方法。
- インダクタを有する共振回路を備えており、前記インダクタを通過する電流の方向が関連の制御スイッチの状態に依存するコンバータであって、
