    • 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.
    • 提供了一种控制电路,包括具有连接在脉冲发生器和第二开关元件之间的电容器的触发电路,以及在负载与第一开关元件的接点与第二开关元件的控制端子之间通过二极管连接的锁存电路 开关元件,其中当所述脉冲发生器输出驱动信号时,所述第一开关元件和所述第二开关元件都被接通,并且所述第二开关元件通过所述锁存电路通过所述接点处的电压保持在ON状态。 当驱动信号停止时,第一开关元件和第二开关元件都断开; 同时如果负载短路,则第一开关元件和第二开关元件通过锁存电路通过接点处的电压而截止。
