What is the working principle of high power triode for high-speed punch press?

    High-power triode in high-speed press mainly plays the role of switching and amplifying signals.
    The working principle is as follows:

     It has three electrodes, namely, base (B), collector (C) and emitter (E). When a small current or voltage signal is applied to the base electrode (control signal), it causes a large change in the current between the collector and emitter.

    In the control circuit of a high-speed punch press, precise control of the current from the collector to the emitter is realized by controlling the base signal, so as to achieve the purpose of switching action or power regulation of certain actuating parts (e.g., solenoid, etc.). This characteristic of controlling large current or power through small signals makes high power transistors play an important role in the circuit system of high-speed presses to realize efficient and accurate control and operation.
