Title: 選択スイッチ装置、これを利用した電源供給装置、及びそのスイッチング方法
IPC: H02J9/06
Filed: 2008-10-31
Abstract: 本発明は、無停電電源供給のための選択スイッチ装置と、その選択スイッチ装置を利用した電源供給装置、及びそのスイッチング方法に関し、複数の電源供給源（Ｓｏｕｒｃｅ）から出力される電源を選択的に負荷に供給する選択スイッチ装置の構造を改善して、より安定的かつ安全に負荷に電源を供給することができるようにしようとする。   このために、本発明の無停電電源供給のための選択スイッチ装置は、半導体スイッチ（例えば、ＳＣＲ（Ｓｉｌｉｃｏｎ  Ｃｏｎｔｒｏｌｌｅｄ  Ｒｅｃｔｉｆｉｅｒ）スイッチ）で構成されていた既存の選択スイッチ装置に、並列に機械的（または電気的）接点スイッチを備えて、半導体スイッチのオン・オフ時、機械的（または電気的）接点スイッチを共にオン・オフさせて半導体スイッチの動作時間（使用時間）を最小化させることにより、半導体スイッチによる問題や故障を減少させる。   また、本発明の無停電電源供給のための選択スイッチ装置は、単純に並列に機械的な（または電気的である）接点スイッチを備えた場合に発生する問題、すなわち、電源供給経路の切り替え時に、各電源供給源が同時に投入される問題を防止するために、スイッチング手段の異常が発生した電源供給源から当該スイッチング手段が電気的、機械的に完全に分離され得るようにして、スイッチング手段による重ね合わせが発生されないように電源供給経路の切り替えを行うことにより、安定的かつ連続的な電源供給が可能なようにする。
