Beschreibung
Zusammenfassung:	The utility model discloses a voltage clamp control circuit. The voltage clamp control circuit is characterized in that a first branch and a second branch are externally connected with alternating current through a port A and a port K; one end of the first branch circuit is connected with a port A of alternating current and a negative electrode of a diode D3, and the other end of the first branch circuit is connected with a port K of the alternating current, one end of a resistor R2, an energy storage capacitor C1 and a negative electrode of a voltage-regulator tube D4; the other end of the resistor R2 is respectively connected with the other end of the energy storage capacitor C1, the positive electrode of the diode D3 and the positive electrode of the voltage-regulator tube D4; one end of the resistor R3 is connected with the positive electrode of the voltage-regulator tube D4, and the other end of the resistor R3 is connected with the emitting electrode and the base electrode of the photoelectric triode Q1
