Description
技術分野
本発明は、パワーエレクトロニクスの分野に関する。独立請求項の序文に係る、コンバータ回路の少なくとも1つの相電圧源によって励振されるアークを除去するための方法に基づく。
コンバータ回路は、今日では典型的にコンバータユニットを有し、前記コンバータユニットの交流電圧側には少なくとも2つの位相接続が設けられ、それにより対応する交流電圧を提供するための相電圧源を前記位相接続に接続することが可能となる。コンバータユニットの直流電圧側では、コンバータ回路は、たとえば1つ以上の容量性エネルギ蓄積装置によって形成されるエネルギ蓄積回路を典型的に備える。
したがって発明の目的は、コンバータ回路の少なくとも1つの相電圧源によって励振されるアークを除去するための方法を特定することにあり、当該方法により、コンバータ回路で生じるアークを特に容易かつ迅速に除去することができる。
図1は、発明に係る方法に従った、例示される短絡電流経路を有するコンバータ回路の第1の実施の形態を示す。図2〜図4は、コンバータ回路の第2、第3、および第4の実施の形態をそれぞれ示し、これらのコンバータ回路の各々において、発明に係る方法に従った、想定される短絡経路が例示される。図1〜図4に示されるコンバータ回路のそれぞれの想定される短絡経路は、太字で例示される。概して、コンバータ回路1は、コンバータユニット2、少なくとも1つの相電圧源3、およびエネルギ蓄積回路4を有し、少なくとも1つの相電圧源3は、コンバータユニット2の交流電圧側に接続される。相電圧源3の接続は、コンバータユニット2の交流電圧側の位相接続Aにおいて行われる。図1〜図4に示されるコンバータ回路はすべて三相設計を有するため、いずれの場合も三相電圧源3も設けられ、概して、上述したように、少なくとも1つの相電圧源3が設けられる。さらに、コンバータユニット2は概して多数の作動可能な電力用半導体スイッチを有し、図1によれば、作動可能な電力用半導体スイッチとしてサイリスタが使用され、図2によれば、ゲート転流型ターンオフサイリスタ(integrated gate-commutated thyristors)(IGCTs)が使用される。対照的に、図3に示されるコンバータ回路の場合、好ましくは絶縁ゲートバイポーラトランジスタ(IGBT)およびサイリスタが作動可能な電力用半導体スイッチとして使用され、想定される短絡経路はその場合、図3に例示されるサイリスタを介して動作する。好ましくは、図4に示されるコンバータ回路の場合も、作動可能な電力用半導体スイッチとしてIGCTを使用することができ、その場合、想定される短絡経路はIGCTを介して動作する。
