Description
図1は、本発明の実施の形態1に係る車載用充電器の要部を示す説明図である。図1を参照して、実施の形態1の車載用充電器100について説明する。
フルブリッジ回路21は、4個のスイッチング素子Q1〜Q4により構成されている。個々のスイッチング素子Q1〜Q4は、Nチャネル型のMOSFET(Metal−oxide−semiconductor Field Effect Transistor)により構成されている。
従来の車載用充電器は、実施の形態1の故障判定モードに対応する動作モードを有しておらず、スイッチングモードによる動作中に異常状態(すなわち過電流が流れている状態)を検出した場合、充電停止モード、充電開始モードを経由して、再びスイッチングモードに移行していた。このとき、スイッチングモードにて所定回数連続して過電流が検出された場合に、直流直流変換部が故障したと判定し、動作モードを充電停止モードに固定するとともに故障信号を送信していた。
実施の形態1の車載用充電器100は、故障判定モードにおいて、高電位側のスイッチング素子Q1,Q3における短絡故障の有無を判定するとともに、低電位側のスイッチング素子Q2,Q4における短絡故障の有無を判定するものであった。実施の形態2では、故障判定モードにおいて、個々のスイッチング素子Q1〜Q4における短絡故障の有無を判定する車載用充電器100について説明する。なお、実施の形態2に係る車載用充電器100の回路構成等は実施の形態1と同様であるため、図1及び図2を援用して説明する。また、実施の形態1と同様の構成部材には同一符号を付して説明を省略する。
