Abstract

　レギュレータＡ、レギュレータＢおよびレギュレータＣの出力電圧は、各負荷素子に供給されるとともに、専用の常駐電源で動作する代表値決定論理回路へと入力される。代表値決定論理回路は、レギュレータＡ、レギュレータＢおよびレギュレータＣの出力電圧から、最も異常であると推定される出力電圧を選択して、選択結果をセレクタに通知する。セレクタは、代表値決定論理回路によって選択された最も異常であると推定される出力電圧を出力するレギュレータからの出力電圧のみを選択して平滑化回路へと出力する。そして、平滑化回路によって平滑化された直流電流は、ＡＤコンバータによって量子化され、システム監視プロセッサへと受け渡される。よって、二次電源をレギュレータに置き換えた場合であっても平滑化回路、ＡＤコンバータ、システム監視プロセッサで構成される電圧監視のための回路は、従来構成と同一のものが使用可能となる。
