    • The inverter device includes an IGBT bridge circuit, a drive block which has an upper arm photocoupler and a lower arm photocoupler, and a control block including a CPU which generates gate signals and supplies them to the photocouplers. The control block includes an upper arm shutdown circuit and lower arm shutdown circuit which individually shutdown the gate signals of the upper arm and lower arm IGBTs in accordance with shutdown signals input from the exterior, and the shutdown circuits carry out a shutdown operation in accordance with the shutdown signals, which have mutually inverted logics.
    • 逆变器装置包括IGBT桥式电路,具有上臂光电耦合器和下臂光电耦合器的驱动块,以及包括产生门信号并将其提供给光电耦合器的CPU的控制块。 控制块包括根据从外部输入的关闭信号单独关闭上臂和下臂IGBT的门信号的上臂关断电路和下臂关断电路,并且关断电路根据 关断信号,具有相互倒转的逻辑。
