Description
図1に示すように、車載用電動圧縮機10のハウジング11内には、流体である冷媒を圧縮する圧縮部12と、圧縮部12を駆動させる電動モータ13とが収容されている。圧縮部12は、例えば、ハウジング11内に固定された図示しない固定スクロールと、固定スクロールに対向配置される図示しない可動スクロールとから構成されるスクロール式である。なお、圧縮部12は、スクロール式に限らず、例えば、ピストン式やベーン式等であってもよい。
制御装置40は、電動モータ13から各ダイオードDu1〜Dw2を介してバッテリ30へ流れる回生電流、各ダイオードDu1〜Dw2のオン電圧、及び各ダイオードDu1〜Dw2の熱抵抗に基づいて、各ダイオードDu1〜Dw2の上昇温度を算出する。
(1)制御装置40は、各ダイオードDu1〜Dw2の破壊を回避するために、算出した各ダイオードDu1〜Dw2の上昇温度に基づいて、電動モータ13の回転数制限値を設定する。そして、制御装置40は、電動モータ13の回転数が回転数制限値を超えないように電動モータ13の回転数を制限する。よって、各ダイオードDu1〜Dw2の破壊を回避するために、例えば、バッテリ30からの入力電圧に応じて電動モータ13の最高回転数を制限する場合、バッテリ30から車載用電動圧縮機10に供給される電力に余裕がある状況においても、バッテリ30からの入力電圧に応じて電動モータ13の最高回転数を制限してしまうといった問題を回避することができる。したがって、車載用電動圧縮機10の運転領域を拡大しつつも、バッテリ30からの入力電圧が低下した場合に、高回転で運転している電動モータ13の停止による各ダイオードDu1〜Dw2の破壊を回避することができる。
○ 図5に示すように、車載用電動圧縮機10は、各ダイオードDu1〜Dw2の温度を検出する温度検出器34を備えていてもよい。温度検出器34は、制御装置40と電気的に接続されており、検出した検出結果を制御装置40に送信する。よって、温度検出器34は、各ダイオードDu1〜Dw2の温度を推定する温度推定部として機能する。
