Working principle

A thyristor is a semiconductor device with a four layer structure, consisting of alternating P-type and N-type semiconductors, forming three PN junctions. Under normal circumstances, the thyristor is in a cut-off state. When a suitable trigger signal is applied to its gate, the thyristor will quickly conduct, allowing current to pass through. When the current decreases to a certain degree or a reverse voltage is applied, the thyristor will automatically turn off, stopping the flow of current. By controlling the timing and pulse width of the gate trigger signal, the conduction time and degree of the thyristor can be accurately controlled, thereby achieving regulation and control of power parameters such as current and voltage.

Precautions for use

Installation requirements: When installing this module, strictly follow the requirements of the product manual to ensure the correct and secure installation position, and avoid mechanical vibration and impact.
