The AC input voltage is transformed by a transformer to obtain low-voltage AC, and then rectified into DC by a thyristor to obtain the required output voltage and current. The control circuit samples the output voltage and output current, and then controls the phase angle of the thyristor trigger conduction moment through the phase control method to keep the output voltage or current stable after closed-loop feedback.
