この実施の形態5では、第2結線26を構成する2枚の負極側ブスバー22、23が1層目と3層目に配置され、第1結線の正極側ブスバー21が2層目、第3結線の中間接続用ブスバー24が4層目に配置されて、積層ブスバーとしての4層ブスバー20aを構成する。即ち、2枚の負極側ブスバー22、23は、正極側ブスバー21を間に挟んで配置され、その外側に中間接続用ブスバー24が配置されている。その他の構成は上記実施の形態4と同様である。
図に示すように、正極側ブスバー21と負極側ブスバー22とが隣接して、しかも電流の流れる方向が対向する。また、負極側ブスバー23と中間接続用ブスバー24とが隣接して、しかも電流の流れる方向が対向する。
次に、この発明の実施の形態6による電力変換装置を図12、図13に基づいて以下に説明する。図12は、この発明の実施の形態6による電力変換装置の構成を示す側面図であり、この電力変換装置の等価回路図を図13に示す。
この実施の形態6では、第2結線26を構成する2枚の負極側ブスバー22、23が2層目と4層目に配置され、第1結線の正極側ブスバー21が1層目、第3結線の中間接続用ブスバー24が3層目に配置されて、積層ブスバーとしての4層ブスバー20bを構成する。即ち、2枚の負極側ブスバー22、23は、中間接続用ブスバー24を間に挟んで配置され、その外側に正極側ブスバー21が配置されている。その他の構成は上記実施の形態4と同様である。
図に示すように、正極側ブスバー21と負極側ブスバー22とが隣接して、しかも電流の流れる方向が対向する。また、負極側ブスバー23と中間接続用ブスバー24とが隣接して、しかも電流の流れる方向が対向する。
上記実施の形態1~6では、4枚のブスバー11~14(21~24)の外形をほぼ同一形状に形成したが、異なる形状に形成しても良い。
図14は、この発明の実施の形態7による電力変換装置の構成を示す側面図である。図に示すように、4層ブスバー10cは、2枚の正極側ブスバー11a、12と、1枚の負極側ブスバー13と、1枚の中間接続用ブスバー14aとの4枚のブスバー11a、12、13、14aを、各ブスバー間にそれぞれ絶縁層15を配して密接に積層して構成される。2枚の正極側ブスバー11a、12は、1層目と4層目に配置されて並列接続され、コンデンサ直列回路CAの正極CPと電力変換部QAの正極QPとを結線する第1結線16aを構成する。負極側ブスバー13は3層目に配置され、コンデンサ直列回路CAの負極CNと電力変換部QAの負極QNとを結線する第2結線となる。中間接続用ブスバー14aは2層目に配置されて、平滑コンデンサCF1(の負極)と平滑コンデンサCF2(の正極)とを直列に接続する第3結線となる。この場合、1層目に配置された正極側ブスバー11aと2層目に配置された中間接続用ブスバー14aは、他のブスバー12、13よりも短く形成されている。その他の構成は、上記実施の形態1と同様である。
なお、正極側ブスバー11a、中間接続用ブスバー14aにおいて省略される領域の大きさは、各ブスバー11a、14aの面積低減による配線インダクタンスの上昇が悪影響を与えない程度に決定される。
