Description
以上の3レベルインバータの回路例については、特許文献1に、またIGBTの電源短絡電流保護方式については特許文献2に、各々示されている。
さらに、ブロック26でアーム短絡検知が行われ,さらにブロック29で2レベル運転中であった場合は,インバータ運転の継続は不可であるため,システム停止する(ブロック34)。以上の説明のように、双方向スイッチが故障した場合には、故障した双方向スイッチを機械的スイッチやヒューズなどで切り離し、残りの双方向スイッチにはオフ信号を与え、半導体スイッチ直列回路の素子(メイン素子)が健全であれば、2レベルインバータとして運転を継続する。
尚、本実施例では半導体スイッチ素子をIGBTとしたが,MOSFETやGTOなどでも実現できる。
