Abstract
【解決手段】DC−DCコンバータ50Aは、基準電圧以上の入力電圧(高回生電圧)を第一電圧に昇圧する効率が、DC−DCコンバータ50Bにより基準電圧以上の入力電圧(高回生電圧)を第一電圧に昇圧する効率よりもよく、DC−DCコンバータ50Bは、基準電圧未満の入力電圧(低回生電圧)を第二電圧に昇圧する効率が、DC−DCコンバータ50Aにより基準電圧未満の入力電圧(低回生電圧)を第二電圧に昇圧する効率よりもよい。そして、電圧変換装置1は、入力電圧が基準電圧以上の場合、DC−DCコンバータ50Aにより入力電圧を昇圧させ、入力電圧が基準電圧未満の場合、DC−DCコンバータ50Bにより入力電圧を昇圧させる。
