Zero type rectifier and voltage stabilizing circuit diagram

The voltage regulator tube of this circuit is connected in front of capacitors and resistors. The voltage regulator tube is connected to the AC power supply through the input capacitor in its conduction direction, and limits the current in the blocking direction to recharge the connected capacitor , thereby stabilizing the output voltage. The voltage ripple of this circuit is larger than that of the bridge type, but because it is directly connected to the AC power supply, the current consumption is smaller.
