Abstract
Description
ジュールのスイッチング素子から構成される上下アームの近傍に電流検出器を実装できるので電力変換装置を小型化できるといった効果を奏するものである。
図1はこの発明の実施の形態に係る電力変換装置付き回転電機を示す断面図である。機電一体型の電力変換装置付き回転電機1は、回転電機2と電力変換装置3とを備えている。回転電機2には、交流発電電動機(モータジェネレータ)が含まれる。回転電機2は、筒状の固定子4と、固定子4の内側に配置され、固定子4に対して回転する回転子5と、固定子4及び回転子5を支持する金属製のケース(支持体)6から構成されている。ケース6は、フロントブラケット7とリヤブラケット8とに分かれる。固定子4はフロントブラケット7及びリヤブラケット8に挟まれている。フロントブラケット7及びリヤブラケット8は、複数の締結ボルト9で締め付けられている。
実施に形態2におけるパワーモジュール23の実装形態について、図6を用いて説明する。実施の形態1では、パワーモジュール23のP端子23aと、N端子23bが絶縁樹脂37の別々の縁から導出されていたが、実施の形態2では、P端子23aとN端子23bは同一の縁から導出されている。この構成により、P端子からN端子までの回路の経路が最も短くできるため、インダクタンスを小さくすることができる。
図7は実施の形態3を示すパワーモジュール23の電気回路図を示す。実施の形態1および実施の形態2では、下アームとN端子23bとの間に電流検出器38を配設してあるが、ここでは上下アームの中間点とAC端子23cとの間に電流検出器38を配設している。この構成により、上アーム(第1のスイッチング素子36a)と下アーム(第2のスイッチング素子36b)に流れる電流値をそれぞれモニターできるため、電力変換装置におけるより精度の高い制御が可能になる。
