Abstract
Description
図1は、この発明の実施の形態1に従う電源装置の概略構成を示す図である。
図2を参照して、交流電源1から正常に電力が供給される通常時には、制御装置20は、スイッチ回路11を構成する半導体スイッチング素子SW1〜SWnに対して、Hレベルの制御信号S1〜Sn(導通指令)をそれぞれ与える。半導体スイッチング素子SW1〜SWnがオンすることにより、スイッチ回路11がオン状態となり、交流電源1および負荷2が電気的に接続される。この結果、図中に矢印で示すように、交流電源1からの交流電力はスイッチ回路11を経由して負荷2に供給される。
図3を参照して、交流電源1からの交流電力の供給が停止された停電時、または交流電源1の供給電圧が瞬間的に低下する瞬時電圧低下の発生時、バッテリ3の直流電力が双方向コンバータ12によって交流電力に変換され、その交流電力が出力端子T2を介して負荷2に供給される。
実施の形態2では、遮断異常判定処理を実行する判定部の第2の構成例について説明する。
実施の形態3では、遮断異常判定処理を実行する判定部の第3の構成例について説明する。
上述した第1から第3の制御構成例の判定部22A〜22Cによる遮断異常判定処理によれば、入力電圧Vinおよび出力電圧Voutの電圧差が小さい場合には、遮断不能となる半導体スイッチング素子SWの端子間電圧Vと、正常にオフされた半導体スイッチング素子SWの端子間電圧Vとの間に有意差が現れないため、遮断異常を検知することが困難となる。
