Abstract
Description
(図1)
電力変換回路を構成する複数の回路体1は、それぞれIGBT(Insulated Gate Bipolar Transistor)やMOSFET(Metal-Oxide-Semiconductor Field-Effect Transistor)などの半導体素子によって構成される。直列接続された2つの回路体1と1つのキャパシタ2が対になることでそれぞれ1相分の回路になり、3相の電力変換回路を構成している。それぞれの回路は、正極配線3および負極配線4と接続されている。
電力変換装置100は、複数のパワー半導体素子をそれぞれ有する複数の回路体1と、回路体1に電気的に接続され、厚さ方向に複数の正極配線3および負極配線4がそれぞれ積層されて設けられる配線基板6(以下基板6)と、複数の回路体1にそれぞれ対応して設けられる複数の平滑キャパシタ2と、を備えている。正極配線3および負極配線4は、基板6の厚さ方向(図2の紙面手前-奥方向)に互いに積層され、かつ各相のキャパシタ2と回路体1を接続する(詳細は図4~図8で後述)。なお、図2は、回路体1を4つずつ並列配置し、8つの回路体1を1相の回路として、3相分を基板6上に備えた構成例を示している。このように、所望の出力電流値に応じて、回路体1は多並列接続する配置にしてもよい。
基板6は、複数の回路体1および複数の平滑キャパシタ2がそれぞれ接続される複数の積層配線部15と、複数の積層配線部15の間にそれぞれ形成される相間配線部16とを有している。積層配線部15において、正極配線3と負極配線4は互いに重なって積層しているが、相間配線部16においては、複数の正極配線3と複数の負極配線4は基板6の平面においてそれぞれ分かれ、かつ並行に配線されてそれぞれ積層している。つまり、相間配線部16は、正極配線3と負極配線4は基板6の厚さ方向に互いに積層されていない領域である。
図4に示すように、積層配線部15では、例えば基板6の導体層が4層の場合、基板6の上面から1層目と3層目が正極配線3、2層目と4層目が負極配線4となる。このように、積層配線部15は、正極配線3と負極配線4が互いに重なって積層している領域である。一方で、図5に示すように、相間配線部16は、積層配線部15同士の間に設けられる領域であり、正極配線3と負極配線4は重ならずにそれぞれの配線同士で積層している。また、相間配線部16は、基板6の厚さ方向に設けられているビア5により、正極配線3と負極配線4それぞれ同電位の配線同士を、基板6の上から下まで互いに電気的に接続している。
(図6)
積層配線部15は、ブラインドビア5aを用いて各配線を積層させることができる。つまり、基板6の上面から1層目と2層目を正極配線3、3層目と4層目を負極配線4として、それぞれ同電位の配線をブラインドビア5aで接続する構成にすることで、正極配線3および負極配線4の断面積を低下させずに、正極配線3と負極配線4をそれぞれ積層することができる。
基板6の一方の面には、複数の回路体1を冷却する冷却器14が配置される。冷却器14と基板6の間には、絶縁性の放熱部材13が設けられる。放熱部材13は、基板6の段差や反りに追従して密着性を向上させる部材であるため、低硬度の樹脂などが用いられる。また、冷却器14は、アルミなど熱伝導率の高い材料により構築される。これにより、正極配線3および負極配線4へ電流を流した際に生じる熱は、相間配線部16のビア5を介して基板6から放熱部材13を介して冷却器14へと放熱されるため、基板6の配線温度を低減できる。
積層配線部15では、基板6の厚さ方向に対して、複数の正極配線3と負極配線4が互いに重なり合うことでそれぞれの配線が積層している。一方で、相間配線部16では、基板6の厚さ方向に対して、複数の正極配線3と負極配線4は重ならず、それぞれの配線同士で積層されており、正極配線3と負極配線4は、基板6の平面において互いに並行するように配置される。また、相間配線部16では、正極配線3と負極配線4それぞれに同電位の配線を接続するビア5が設けられている。
(図9)
図9は、ハイサイド側の回路体1とローサイド側の回路体1をそれぞれ一体化した構成例である。これにより、回路体1を基板6へ容易に実装でき、かつ各相の配線インダクタンスの低減と基板6の温度低減を両立できる。
