Abstract
Description
図1は、本発明の実施の形態1に係る電力変換装置の回路構成例を示す図である。
DCDC昇圧コンバータ回路10の半導体スイッチング素子13a〜13dをスイッチング動作させた場合、昇圧リアクトル12が有する2つの巻線122にはリプル成分を持った電流が流れる。そのため、昇圧リアクトル12が発生させる磁束F1は、このリプル成分に応じて変化する。昇圧リアクトル12が発生する磁束F1を完全に遮蔽できない場合、その磁束F1の変化は、電流値の検出結果に含まれる誤差の大きさを変動させ、磁気シールド板24を発熱させる。このことから、本実施の形態2は、電流値の検出結果に含まれる誤差の大きさの変動を抑制して、精度をより向上させると共に、磁気シールド板24の発熱をより抑えるようにしたものである。ここでは、上記実施の形態1と同じ、或いは相当する構成要素には同じ符号を付し、異なる部分について詳細に説明する。これは、後述する他の実施の形態でも同様とする。
図8は、本発明の実施の形態3に係る電力変換装置におけるバスバを含む周辺の構成例と昇圧リアクトルとの間の位置関係例を示す斜視図である。
図9は、本発明の実施の形態4に係る電力変換装置におけるバスバを含む周辺の構成例と昇圧リアクトルとの間の位置関係例を示す斜視図である。
