Abstract
Description
急速型とは、MODE1矩形波信号を用いた放電によって電圧平滑用コンデンサ2に溜まった電荷の急速な放電が可能なように、MODE1矩形波信号のデューティを設定するものである。急速型においては、MODE1矩形波信号のデューティを90%程度と大きく設定する。例えば、MODE1矩形波信号のデューティを95%と設定すると、MODE1矩形波信号の反転信号であるMODE2矩形波信号のデューティは5%となる。
バランス型とは、MODE1矩形波信号のデューティを60%程度に設定し、MODE1およびMODE2のどちらにおいても放電終了時間に大きな差がでないような設定である。バランス型の特徴は、モータコントローラ5が故障した場合にMODE1およびMODE2のいずれで放電されても放電終了時間に大きな差が生じないので、感電による二次災害の危険性を減らせることである。
