It uses LM324 operational amplifier A as the measurement comparison and control circuit. When the grid
voltage is lower than the set value (set by the potentiometer RP), pin 1 of A outputs high level, the transistor VT is turned on, the relay
KA is closed, and the output voltage is the sum of the grid voltage and the secondary voltage of the transformer; When the grid voltage is higher than the set value, KA is released
and the output voltage is the same as the grid voltage, so it is a voltage regulator suitable for low grid voltage.
