Abstract
Description
ケース(C)内に、
電力変換回路を構成する半導体モジュール(2)と、
上記半導体モジュールを冷却するための冷却器(3)と、
上記半導体モジュールと電気的に接続されたコンデンサモジュール(4)と、
上記コンデンサモジュールに蓄積された電荷を放電するための放電抵抗(51)が実装された放電抵抗基板(5)と、
上記半導体モジュールの動作を制御する制御回路基板(6)と、を収容する電力変換装置(1)であって、
上記放電抵抗基板は、上記コンデンサモジュールの外壁面(40A)と上記制御回路基板との間において、上記外壁面及び上記制御回路基板から離れて位置し、かつ上記制御回路基板に対して垂直に配置されている、電力変換装置にある。
なお、特許請求の範囲及び課題を解決する手段に記載した括弧内の符号は、後述する実施形態に記載の具体的手段との対応関係を示すものであり、本発明の技術的範囲を限定するものではない。
電力変換装置に係る実施形態について、図1〜図7を参照して説明する。
図1に示すように、本形態における電力変換装置1は、ケースC内に、電力変換回路を構成する半導体モジュール2と、半導体モジュール2を冷却するための冷却器3と、半導体モジュール2と電気的に接続されたコンデンサモジュール4と、コンデンサモジュール2に蓄積された電荷を放電するための放電抵抗51が実装された放電抵抗基板5と、半導体モジュール2の動作を制御する制御回路基板6と、を収容して構成される。
なお、本形態では、制御回路基板6に対し垂直方向に延在する放電抵抗基板5の延在方向(例えば、図3上図の上下方向)をZ方向とし、これと直交する方向のうち、半導体モジュール2及びコンデンサモジュール4の長手方向(例えば、図3上下図の左右方向)をX方向とする。また、半導体モジュール2及びコンデンサモジュール4の幅方向(例えば、図3下図の上下方向)をY方向とする。
図5に回路構成例を示すように、本形態の電力変換装置1は、昇圧用のコンバータ11及び交流変換用のインバータ12を備え、バッテリBの高圧直流電力を昇圧して三相(すなわち、U相、V相、W相)の交流電力に変換する。
このような電力変換装置1は、例えば、ハイブリッド自動車、電気自動車等の電動車両に適用されて、車両走行用のモータMに電力を供給するための装置として用いられる。
第2ケースC2の内側には、コンデンサモジュール4と、出力端子台16が配置される。また、図示しないリアクトルL等が収容される。
入力バスバ44と、正極側バスバ45及び負極側バスバ46は、コンデンサケース40の頂壁面40Aに対して同じ側に設けられる。また、基板固定部43は、頂壁面40Aの概略中央部に配置される。なお、これらの配置は一例であり、適宜変更することができる。
このように、放電抵抗基板5の基板面52が、コンデンサモジュール4の頂壁面40A及び制御回路基板6の基板面61から離れて、それぞれと垂直な方向に延在するように、独立に設けられる。これにより、互いの電気的接続を保ちながら、放電抵抗基板5に実装される放電抵抗51を、コンデンサモジュール4を構成するコンデンサ素子から遠ざけることができる。したがって、放電抵抗51からの受熱によるコンデンサ素子の温度上昇を抑制し、コンデンサ素子の劣化を抑制して、長寿命化を図ることができる。
また、電圧検出端子13a〜13dを放電抵抗基板5の延在方向に配置し、基板固定部43にこれらを支持する端子保持部43Aを設けることで、ケースC内にコンパクトに収容することができる。
これにより、ケースC内の空間を有効活用でき、あるいは、ケースC内の空間体積を最小限として装置の小型化が可能になる。
