Description
図1は、この発明の実施の形態1による無停電電源装置1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1は、商用交流電源21からの三相交流電力を直流電力に一旦変換し、その直流電力を三相交流電力に変換して負荷24に供給するものであるが、図面および説明の簡単化のため、図1では一相分の回路のみが示されている。
実施の形態1では、波形歪発生モードが選択された場合、負荷24にとって許容範囲内の波形歪を有する交流電圧VOを負荷24に印加して、無停電電源装置1の効率ηを高めた。この実施の形態2では、波形歪発生モードが選択された場合、さらに、無停電電源装置1の効率ηが良くなるように出力電圧VOのレベルを制御する。
