Abstract
Description
図1Aは、この発明の実施の形態1に係る電力変換装置の回路構成を示した構成図である。また、図1Bの(a)は、この発明の実施の形態1に係る電力変換装置に設けられた第1の導体および第2の導体の構成を示した平面図であり、(b)は、(a)のA−A断面図である。
この発明の実施の形態2に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態3に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態4に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態5に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態6に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態7に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態8に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
この発明の実施の形態9に係る電力変換装置の全体の構成は、上記の図1Aに示した実施の形態1の構成と同一である。
なお、上記の実施の形態6〜9においては、第1の導体105と第2の導体106を板状または角柱型の金属バスバーから構成したが、図12Aの(b)に示すように、円柱型の金属バスバーから第1の導体105および第2の導体106を構成することで、導体間の寄生容量をさらに小さくすることができる。例として、図12Bに、角柱型と円柱型による2本の導体間容量の比較結果を示す。角柱型は幅d、高さd、長さLの2本の金属導体を、距離gだけ離間させて配置する。円柱型も角柱型と同様に、幅d、高さd、長さLの2本の金属導体を、距離gだけ離間させて配置する。図12Bに示されるように、第1の導体105と第2の導体106を円柱型にすることで、第1の導体105と第2の導体106間の寄生容量109が小さくなることが分かる。
