The figure shows an AC voltage regulator circuit composed of bidirectional thyristors. Compared with the unidirectional thyristor regulator, the circuit is simple and reliable. When the grid voltage is less than 220V, the voltage on the control pole of the triac SCR2 also decreases with the decrease of the grid voltage, resulting in a small conduction angle of VD2 and a voltage rise at the C1 terminal, thereby increasing the control voltage of the triac SCR1. To increase the output voltage. Conversely, the output voltage drops and reaches regulation.
