摘要： A control circuit is provided including a trigger circuit having a capacitor connected between a pulse generator and a second switching element, and a latch circuit connected via a diode, between a junction of a load with a first switching element and the control terminal of the second switching element, wherein when the pulse generator outputs a drive signal, both of the first switching element and the second switching element are turned on and the second switching element is held in the ON state through the latch circuit by a voltage at the junction. When the drive signal is stopped, both of the first switching element and the second switching element are turned off; meanwhile if the load is short-circuited, the first switching element and the second switching element are turned off through the latch circuit by the voltage at the junction.

摘要： An internal-combustion-engine electronic control system according to the present invention is provided with a power switching device that applies or shuts off a primary current of an ignition coil of an internal combustion engine so that at the secondary side of the ignition coil, there is generated a voltage for making an ignition plug of the internal combustion engine produce a spark discharge; and a control unit that turns on or off the power switching device. The internal-combustion-engine electronic control system is characterized in that the control unit is provided with a circuit unit that makes the power switching device softly shut off so as to prevent the ignition plug from producing the spark discharge, and in accordance with the characteristics of the power switching device, the control unit changes the characteristics of the soft shutoff halfway through the shutoff operation.
摘要翻译：根据本发明的内燃机电子控制系统设置有电源切换装置，其施加或切断内燃机的点火线圈的初级电流，使得在点火线圈的二次侧产生用于使内燃机的火花塞产生火花放电的电压; 以及控制单元，其接通或断开电力开关装置。内燃机电子控制系统的特征在于，控制单元设置有使电源开关装置软关闭的电路单元，以防止火花塞产生火花放电，并且根据特性的电源切换装置，控制单元通过关闭操作中途改变软关断的特性。
