摘要： PURPOSE:To increase the off-control ability, without increasing an off-drive current, by connecting a diode in forward direction in series with a cathode of a PNPN switch. CONSTITUTION:A collector of a TR8 and an anode of a diode 7 are respectively connected to a cathode-gate and a cathode of a PNPN switch 6, and the emitter of the TR8 and the cathode of the diode 7 are connected. In turning off the PNPN switch 6 from conduction, a current flows to a base 9 of the TR8 to drive the TR8 to remove the current from the cathode-gate of the switch 6. In this case, a voltage between the collector and emitter of the TR8 can be taken larger by the forward voltage drop of the diode 7, allowing to prevent the saturation of the TR8.

摘要： PURPOSE:To save and reduce power consumption of a gate turn-OFF control circuit by detecting the fact that a P-N-P-N type switch which has gate turn- OFF function has completed the gate turn-OFF, and stopping the operation of a gate turn-OFF circuit. CONSTITUTION:A voltage is generated between the gate and the cathode of a P-N-P-N switch 16 when the switch 16 is conducted, a transistor TR14 is driven, and a collector current is flowed. This current drives the base of a TR5, and when a TR6 is turned OFF, TR10 is turned OFF. The base of a TR12 is driven, the collector current of the TR12 drives the base of the TR13, and the switch 16 is opened. When the switch 16 is opened, the TR14 is interrupted, and the TR10 is also interrupted. Accordingly, the OFF drive is stopped. When the OFF drive is not operated, the TR6 is turned ON from a terminal 2. In this manner, the OFF drive current does not flow after the completion of the gate turn OFF, thereby saving the power consumption.
摘要翻译：目的：通过检测具有闸极关断功能的PNPN型开关已完成门关断的事实，并且停止栅极关断的操作来节省和降低门极关断控制电路的功耗电路。构成：当开关16导通时，P-N-P-N开关16的栅极和阴极之间产生电压，驱动晶体管TR14，并且集电极电流流动。该电流驱动TR5的基极，当TR6关闭时，TR10关闭。 TR12的基极被驱动，TR12的集电极电流驱动TR13的基极，开关16断开。当开关16断开时，TR14中断，TR10也中断。因此，OFF驱动停止。当OFF驱动器不工作时，TR6从端子2接通。以这种方式，在门关闭完成之后，OFF驱动电流不流动，从而节省功耗。
