    • A problem to be solved by the present invention is to eliminate variation in potential in a turn-off time period of each GTO element, and to stabilize a gate drawing current by surely performing the turn-off of the GTO element. In an inverter apparatus (11) having a three-phase inverter (14) configured to include paired GTO elements UP, UN, VP, VN, WP, and WN connected in a bridge configuration and to convert a power supply voltage, which is supplied from a dc power supply (13), by the GTO elements UP, UN, VP, VN, WP, and WN into an ac voltage, an inverter control portion has a simultaneous switching prevention function of delaying a turn-on operation of each of the GTO elements VN and WN, which correspond to phases other than a phase corresponding to an optional one of the GTO elements and also correspond to an electrode opposite to an electrode corresponding to the optional one of the GTO elements, for example, the GTO element UP, by a predetermined time in a case where a turn-on command signal for turning on each of the GTO elements VN and WN, which correspond to the other phases, is generated within a predetermined time period since the turn-off of the optional one of the GTO elements.
    • 本发明要解决的问题是消除每个GTO元件的关断时间段中的电位变化,并且通过可靠地执行GTO元件的关断来稳定栅极引出电流。 在具有三相逆变器(14)的逆变器装置(11)中,被配置为包括以桥式配置连接的配对GTO元件UP,UN,VP,VN,WP和WN,并且转换供给的电源电压 通过GTO元件UP,UN,VP,VN,WP和WN从直流电源(13)到交流电压,逆变器控制部分具有同时切换防止功能,延迟每个的接通操作 GTO元件VN和WN,其对应于除了与GTO元件中的任选一个相对应的相位之外的相位,并且还对应于与对应于GTO元件中的任选一个的电极相对的电极,例如GTO元件 在从可选择性的关闭之后的预定时间段内产生用于接通与其他相位对应的GTO元件VN和WN的每个的导通命令信号的情况下的预定时间 其中一个GTO元素。
