Principle of Silicon Controlled Rectifier (SCR) Trigger Board

The core principle of the silicon-controlled rectifier (SCR) trigger board is to control the conduction of the SCR through appropriate trigger signals. When a positive trigger signal is applied, the holding current on the SCR is amplified, thereby allowing the SCR to conduct. The trigger signal can be in the form of rectangular pulses, sine waves, square waves, and other types of signals.
