直流電源2から出力された直流電力は、2つのDC/DCコンバータ11a,11bに入力される。電流検出部13a,13bは、対応するDC/DCコンバータ11に入力される電流(コンバータ入力電流)を検出し、検出結果を対応する制御回路12に出力する。また、電圧検出部14a,14bは、共通負荷3の電圧(共通負荷電圧VL)を検出し、検出結果を対応する制御回路12に出力する。電流検出部13および電圧検出部14より検出結果が入力された制御回路12は、これらの検出結果に基づいて、対応するDC/DCコンバータ11の制御を行う。DC/DCコンバータ11は、対応する制御回路12からの制御信号に基づいて入力された直流電力を電力変換し、共通負荷に出力する。以下に、制御回路の動作の詳細を述べる。
実施の形態1では、制御回路が電圧制御部を有する構成について示したが、実施の形態2に示す並列電源装置では、制御回路が電圧制御部に加え、コンバータ入力電流を制御する電流制御部を備える。
