Abstract
Description
図1は、本発明の実施の形態1にかかる電力変換装置の構成例を示す図である。
(コンデンサ10,11の静電容量)<<(コンデンサ17A,17Bの静電容量)…(1)
実施の形態1で説明した電力変換装置100は、主回路コンデンサの電圧が予め定められた電圧となる前の主回路コンデンサの充電経路(第1の充電経路201,第2の充電経路202)を形成するコンデンサ10および11に対して電圧バランス用の抵抗を挿入しない構成とした。しかし、コンデンサ10および11の静電容量比によっては、片方のコンデンサに電圧が偏り、コンデンサ10の電圧とコンデンサ11の電圧がアンバランスになる可能性がある。よって、電圧バランスが偏りコンデンサ10または11の電圧が耐圧を超えるような場合、電圧バランスをとるための抵抗をコンデンサ10および11のそれぞれに並列に実装してもよい。また、コンデンサの充電経路の形成に用いられないコンデンサ9に対しても電源バランスをとるための抵抗を並列に実装してもよい。
図6は、本発明の実施の形態3にかかる電力変換装置の構成例を示す図である。実施の形態1,2にかかる電力変換装置100は、3相4線式の交流電源である電源1から供給される第1の交流電力を第2の交流電力に変換して負荷に供給する構成であった。これに対して、図6に示した実施の形態3にかかる電力変換装置101は、電源31から供給される単相の交流電力を第2の交流電力に変換して負荷に供給する。本実施の形態においては、電源31から供給される単相の交流電力が第1の交流電力となる。
