Abstract
Description
図1は、この発明の実施の形態1による電源装置の構成を示す回路ブロック図である。図1において、この電源装置は、交流ラインL1,L2、半導体スイッチ1、操作部2、制御装置3、および報知部4を備える。
図6は、この発明の実施の形態2による電源装置の構成を示す回路ブロック図であって、図1と対比される図である。図6を参照して、この電源装置が実施の形態1の電源装置と異なる点は、半導体スイッチ1が半導体スイッチ41で置換され、制御装置3が制御装置42で置換されている点である。
図8は、この発明の実施の形態3による瞬低(瞬時電圧低下)補償装置の構成を示す回路ブロック図であって、図1と対比される図である。なお、瞬時電圧低下とは、商用交流電源5からの交流電圧VIが事故(たとえば落雷)によって短時間(たとえば1秒未満)低下することをいう。また、停電とは、商用交流電源5からの交流電圧VIの供給が事故(たとえば落雷)によって長時間(たとえば1秒以上)停止されることをいう。
図9は、この発明の実施の形態4による無停電電源装置61の構成を示す回路ブロック図である。この無停電電源装置61は、バイパス交流電源7(第1の交流電源)から三相交流電力が正常に供給されている健全時には、バイパス交流電源7からの三相交流電力を半導体スイッチ1を介して負荷6に供給し、バイパス交流電源7からの三相交流電力の供給が停止された停電時には、インバータ70によって生成された三相交流電力を負荷6に供給するものである。図9では、図面および説明の簡単化のため、三相(U相、V相、W相)のうちの一相(たとえばU相)に対応する部分の回路のみが示されている。
