The working principle of high-voltage thyristor
A high-voltage thyristor is a four-layer structure consisting of P-type and N-type semiconductors, the core of which is a PN junction. Under the action of external voltage, the holes and electrons in the PN junction diffuse to each other under the movement of the electric field, forming an electric current. 하지만, when the external voltage is reversed, the number of carriers inside the PN junction decreases, and the draft is almost zero. 결과적으로, high-voltage thyristors have unidirectional conductivity. By controlling whether the trigger signal is applied, the high-voltage thyristor can switch between forward conduction and reverse cut-off.
