Abstract
Description
図1は、本発明の実施の形態1に係る電力変換装置の構成例を示す図である。電力変換装置は、パンタグラフ1で集電される交流電力を変圧器3で変圧し、コンバータ4で直流電力に変換したのち、インバータ6で可変電圧、可変周波数の3相交流電力に変換して電動機7を駆動する。電力変換装置は、回生動作も可能である。回生動作では、電動機7からの交流電力を、インバータ6で直流電力に変換し、コンバータ4で交流電力に変換して変圧器3を介してパンタグラフ1から架線側に返す。
図4は、本発明の実施の形態2に係る電力変換装置の構成例を示す図である。実施の形態2では、充電抵抗器10を過電圧抑制用抵抗としても用いる。充電抵抗器10は、実施の形態1と同様に、過電圧信号OVDが発生した場合に過電圧抑制用回路が動作していないと判定されるときに、フィルタコンデンサ5を短絡する抵抗器でもある。
