Abstract
Description
以下、図1~図3を参照して、本発明のDCDCコンバータ一体型充電器の実施形態1を説明する。
図1は、本発明のDCDCコンバータ一体型充電器の回路図である。DCDCコンバータ一体型充電器100は、ハイブリッド自動車、電気自動車等の車両用として用いられる。モータを備えた車両は、DCDCコンバータ一体型充電器100の他、図示はしないが、高電圧バッテリと、高電圧バッテリより低圧な補機バッテリとを備えている。DCDCコンバータ一体型充電器100は、充電器10とDCDCコンバータ回路部310とを有する。充電器10は、外部電源を高電圧バッテリに接続して、高電圧バッテリを充電可能となっている。つまり、充電器10の入力端子421には、外部の交流または直流電源が接続される。また、充電器10の出力端子422は、高電圧バッテリに接続される。DCDCコンバータ回路部310は、充電器10に接続されている。DCDCコンバータ回路部310は、高電圧の直流電力を低電圧の直流電力に変換して補機バッテリに給電する。
DCDCコンバータ回路部310は、補機用の出力端子423を介して補機バッテリに接続される。
図3は、本発明のDCDCコンバータ一体型充電器の実施形態2の外観斜視図であり、図4は、図3のIV-IV線断面図であり、図5は、図3に図示されたDCDCコンバータ一体型充電器の分解斜視図である。DCDCコンバータ一体型充電器100は、第1空間用筐体411と、第2空間用筐体406と、第3空間用筐体402とを有している。第1~第3用筐体411、406、402は、アルミニム合金等の導電性部材により形成されており、図示の通り、三段に積層されている。図4、図5に示されるように、最下段の第1空間用筐体411は、内部に第1空間101を有し、中段の第2空間用筐体406は、内部に第2空間201を有し、最上段の第3空間用筐体402は、内部に第3空間301を有する。
図6(A)は、本発明のDCDCコンバータ一体型充電器の実施形態3の外観斜視図であり、図6(B)は、図6(A)のVIB-VIB線断面図である。
実施形態3の外観は、実施形態2として示す図3と同様である。実施形態3が実施形態2と相違する点は、実施形態2で第1空間101に収容した制御回路部410(図4参照)と同一の機能を有する制御回路部500が、第2空間用筐体406の第2空間201内に配置されている構成を有することである。第2空間201は、第1壁150および第2壁250により、スイッチング回路部110およびDCDCコンバータ回路部310とは隔てられている。このため、スイッチング回路部110およびDCDCコンバータ回路部310で発生するノイズの入・出力回路部210、220への影響を抑制することができる。
図7(A)は、本発明のDCDCコンバータ一体型充電器の実施形態4の外観斜視図であり、図7(B)は、図7(A)のVIIB-VIIB線断面図である。実施形態4のDCDCコンバータ一体型充電器100が、実施形態3と相違する点は、第2空間201に収容した制御回路部500を2つに分割し、それぞれを、第1空間用筐体411の第1空間101内および第3空間用筐体402の第3空間301内に配置した構成を有することである。実施形態4の他の構成は、実施形態3と同様である。従って、実施形態4においても、実施形態2と同様な効果を奏する。なお、実施形態4において、制御回路部500を、ノイズを発生する他の回路から保護するため、シャーシを用いてシールドするようにしてもよい。また、実施形態3と実施形態4とを組み合わせて、制御回路部500を、第2空間201内と他の空間である、第1空間101内または第3空間301内に配置するようにしてもよい。さらに、制御回路部500を、第1~第3空間101、201、301内すべてに配置するようにしてもよい。
図8(A)は、本発明のDCDCコンバータ一体型充電器の実施形態5の斜視図であり、図8(B)は、図8(A)のVIIIB-VIIIB線断面図である。実施形態5が実施形態4と相違する点は、入力端子421と出力端子422が、第2空間用筐体406に取付けられている構成を有することである。上述したように、入力端子421は、入力フィルタ回路部210と接続されている。入力端子421には、交流電力または直流電力が給電される。出力端子422は、出力フィルタ回路部220と接続されている。出力端子422は高電圧バッテリに電力を供給するための出力端子である。実施形態5の他の構成は実施形態4と同様である。従って、実施形態5においても、実施形態4と同様な効果を奏する。なお、入力端子421および出力端子422は、第1空間用筐体411に配置するようにしてもよい。
図9(A)は、本発明のDCDCコンバータ一体型充電器の実施形態6の斜視図であり、図9(B)は、図9(A)の上方からの平面図である。実施形態6が実施形態5と相違する点は、入力端子421と出力端子422が、第2空間用筐体406の異なる側面に配置されている構成を有することである。入力端子421は、第2空間用筐体406の第1の側面471に、その取付部421aが固定されている。出力端子422は、第1の側面471に隣接する第2の側面472に、その取付部422aが固定されている。従って、入力端子421と出力端子422とは、図9(B)に示されるように、その軸方向の角度θが90度、異なる方向を向いている。換言すれば、入力端子421が配置された第1の側面471である入力端子取付面と出力端子422が配置された第1の側面471である出力端子取付面とは、90度、異なっている。
図10(A)、(B)は、本発明のDCDCコンバータ一体型充電器の実施形態7を示し、図10(A)は、筐体を透過し、冷却流路を示す斜視図であり、図10(B)は、図10(A)のXB-XB線断面図である。実施形態7として図示される図10(A)、(B)は、実施形態2の冷却構造を、より詳細に示すものである。実施形態7におけるノイズ干渉の抑制に関する構造は、実施形態2と同様であるので、対応する部材に同一の参照符号を付して説明は省略し、以下は、その冷却構造について説明する。
図10(A)に図示されるように、第2流路251は、第3空間用筐体402の底部402aの周側部に沿ってほぼ環状に設けられ、第1流路151は、第2空間用筐体406の底部406aの周側部に沿ってほぼ環状に設けられている。
(1)第1~第3空間用筐体411、406、402を積層する構造でありながら、冷媒が流れる流路は、導入口431から導出口432まで、1本の流路で連通されている。このため、構造が簡素となり、また、冷却温度の管理が容易となる。
