Energy-saving voltage stabilizing circuit

Abstract

The invention discloses an energy-saving voltage stabilizing circuit. The circuit comprises a transformer T, a diode D1, a rectifier bridge Q, a triode VT1, a diode D2 and a unidirectional silicon controlled rectifier VS1. Two ends of a coil L1 of the transformer T are respectively connected with two ends of 220V alternating current; two ends of a coil L2 of the transformer T are respectively connected with a pin 1 and a pin 3 of the rectifier bridge Q; two taps are arranged on a coil L2 of the transformer T, the tap 1 is connected with the negative electrode of the diode D1, the tap 2 is connected with the negative electrode of the diode D2, the positive electrode of the diode D2 is connected with the positive electrode of the diode D1 and one end of the potentiometer RP1, and the other end of the potentiometer RP1 is connected with a pin 2 of the rectifier bridge Q, the resistor R1, the capacitor C1 and the output end Vo. According to the energy-saving voltage stabilizing circuit, the transformer, the diode and the triode are adopted to be matched with the one-way silicon controlled rectifier for control, the voltage stabilizing effect can be achieved during overvoltage and undervoltage, the circuit structure is simple, the cost is low, and the size is small.
