Abstract
Description
上記車載用流体機械は、前記車載用電動モータによって駆動する圧縮部を備えた車載用電動圧縮機であるとよい。
入力端子31,32は、車載用インバータ装置30と車載用蓄電装置104とを接続するのに用いられるものである。本実施形態では、入力端子31,32は、リレー111,112,114,115を介して車載用蓄電装置104と接続される。詳細には、車両100は、入力端子31,32と車載用蓄電装置104とを接続する車両電源ラインLN11,LN12を有している。リレー111,114は、第1車両電源ラインLN11上に設けられている。リレー112,115は、第2車両電源ラインLN12上に設けられている。なお、本実施形態では、リレー111,112,114,115は、車載用インバータ装置30外に設けられている。
ここで、ドライバ回路71とインバータ回路50との間に流れるリーク電流Irについて図3を用いて説明する。説明の便宜上、図3では、u相上アームスイッチング素子Qu1及びu相下アームスイッチング素子Qu2を示し、他の相のスイッチング素子については図示を省略する。
入力端子31,32に高直流電力P1が入力されていない状況において、ドライバ回路71に低直流電力P2が供給された場合にはu相下アームスイッチング素子Qu2がON状態になる。これにより、図3の実線に示すように、リーク電流Irは、u相上アーム還流ダイオードDu1ではなく、u相下アームスイッチング素子Qu2を流れることとなり、フィルタコンデンサ63にはリーク電流Irは流れない。v相及びw相についても同様である。したがって、フィルタコンデンサ63が充電されにくい。
(1)車載用インバータ装置30は、車載用電源としての車載用蓄電装置104を用いて車載用電動モータ11を駆動する。車載用インバータ装置30は、入力端子31,32と、インバータ回路50と、フィルタ回路60と、制御回路としてのドライバ回路71及びコンプECU72と、を備えている。
○ ドライバ回路71及びコンプECU72は、入力端子31,32に高直流電力P1が入力された場合であっても、下アームスイッチング素子Qu2,Qv2,Qw2をON状態に維持してもよい。
また、フィルタ回路60は、フィルタコンデンサを複数有していてもよい。例えば、フィルタ回路60は、Xコンデンサとしてのフィルタコンデンサ63とは別に、Yコンデンサを有していてもよい。
○ 平滑コンデンサ113を省略してもよい。
○ リレー111,112,114,115は、車載用インバータ装置30外に設けられていたが、これに限られず、車載用インバータ装置30がリレー111,112,114,115を有する構成でもよい。
(イ)入力端子としての第1入力端子及び第2入力端子と、第1入力端子に接続される正極母線と、第2入力端子に接続される負極母線と、上アームスイッチング素子に対して並列に接続される上アーム還流ダイオードと、を備え、上アームスイッチング素子は正極母線に接続されており、下アームスイッチング素子は負極母線に接続されており、上アーム還流ダイオードのカソードは正極母線に接続されており、上アーム還流ダイオードのアノードは接続線に接続されており、フィルタ回路のコンデンサは、正極母線及び負極母線に接続されているとよい。
