としたサイリスタ駆動回路。In a thyristor-based thyristor drive circuit in an inverse variable berth device, a square wave current is obtained through a resistor by a switching element such as a transistor, and an impulse current is obtained by discharging a capacitor at the same time as the square wave current rises. In addition, the thyristor drive circuit uses the thyristor gate drive current.
