Description
ブリッジ整流回路の整流素子にMOS型FETを採用し、発電充電時の電気的損失を低減する従来技術として、例えば特許第2959640号公報(以下、特許文献1と称す。)に示されるものがある。この特許文献1に示されるものは、FETのドレイン・ソース間にドレイン電圧よりも高いソース電圧が印加された場合(逆方向電圧印加時)に、ゲート・ソース間に電圧を印加して、該FETをオンさせて電力損失を低減させるというものである。
このために、判定電圧範囲を狭くせざるを得ず、検出性が悪化するため、FETをオン制御することによりブリッジ整流回路での損失を低減する運転領域を制限せざるを得ないという課題がある。
また、ブリッジ整流回路内の上下のFETの短絡故障による異常な大電流故障時や、始動時の電動機としての動作時での異常電流時からの保護等も制限されるという課題がある。
実施の形態1.
図1は、実施の形態1の充電回路の全体構成図である。
図1において、1は発電電動機を構成する電機子巻線、2は同じく界磁巻線であり、3は車載用バッテリーである。4は界磁巻線1の通電を制御する界磁巻線通電スイッチ、5a〜5fは、発電電動機とバッテリ3との間に接続され電機子巻線1の通電を制御する整流回路を構成するMOS型FFTであり、図中Dはドレイン端子、Sはソース端子、Gはゲート端子である。また、Isは、例えば一般的にセンシングFET等と呼ばれるドレイン−ソース間に流れる電流の一部を分流出力する端子であり、相電流検出端子である。
6a〜6fは、FET5a〜5fに流れる電流とその方向を検出する相電流検出手段、7は、FET5a〜5fのゲートと、界磁巻線通電スイッチ4とを制御する制御手段であるプリドライバ回路である。
尚、相電流検出端子Isは相電流検出手段6a〜6fに接続され、電流とその方向とが相電流検出手段6a〜6fにより各々判定される。
FETでドレイン端子Dからソース端子S方向の順方向であるID方向に電流が流れると、相電流検出端子Isの出力は正方向に出力される。FETでソース端子Sからドレイン端子D方向の逆方向である−ID方向に電流が流れると、相電流検出端子Isの出力は−Isの負方向に出力される。
第3図の、−ID方向(逆方向)の第一の所定値ID1より大きな電流の領域(図中のA領域)を、相電流検出端子Isの出力から相電流検出手段6でIs1として検出することによって、電機子巻線1からの発電状態と判断し、プリドライバ回路7より該FETのゲート端子Gにオン信号を印加し、該FETをオンさせる。これにより該FET内ではソース端子Sからドレイン端子D間の寄生ダイオードのみによる整流動作から、FETのオン状態での低い導通抵抗での整流動作に切り替わり、電力損失が低減される。
5a〜5f:FET、D:ドレイン端子、S:ソース端子、G:ゲート端子、
Is:相電流検出端子、6a〜6f:相電流検出手段、
7:プリドライバー回路(制御手段)、
ID:順方向FET電流、−ID:逆方向FET電流、
Is1:第一の所定値に相当する相電流値、Is2:第二の所定値に相当する相電流値、
A:FETをオンする領域、B:FETをオフする領域。
