Abstract
Description
図面を参照しながら実施形態に係る車両電源装置1について説明する。図1は、実施形態に係る車両電源装置1の構成例を示すブロック図である。図2は、実施形態に係る車両電源装置1の充電例を示すブロック図である。図3は、実施形態に係る車両電源装置1の放電例を示すブロック図である。
次に、実施形態の変形例について説明する。なお、変形例では、実施形態と同等の構成要素には同じ符号を付し、その詳細な説明を省略する。図5は、実施形態の第1変形例に係る車両電源装置1Aの構成例を示すブロック図である。第1変形例に係る車両電源装置1Aは、定圧DC/DC変換部60Aが3相の降圧チョッパ回路CP2を備える点で実施形態に係る車両電源装置1と異なる。3相の降圧チョッパ回路CP2は、図5に示すように、電流を通電又は遮断する3つのスイッチング素子61と、3つのダイオード62と、各スイッチング素子61の動作に応じて各ダイオード62を介して誘導電流を出力する3つのコイルから成る結合インダクタ63とを有する。定圧DC/DC変換部60Aは、3相の降圧チョッパ回路CP2において、1/3の降圧比で中間電圧Vmを降圧する。中間電圧Vmは、例えば、低圧負荷部4の電圧の最大値を15Vとし、相数を3相とした場合、当該中間電圧Vmの最大値が45Vとなり、4相の降圧チョッパ回路CP1の中間電圧Vm(60V)よりも小さくなる。これにより、3相の降圧チョッパ回路CP2は、4相の降圧チョッパ回路CP2よりも電圧を扱い易くなるが、電力損失の点で4相の降圧チョッパ回路CP2よりも劣る。
