Abstract

The invention discloses an automatic alternating current voltage-stabilizing power supply with a stable performance. The automatic alternating current voltage-stabilizing power supply is characterized by mainly comprising a voltage regulator T, a diode rectifier U1, a servo motor M, a polar capacitor C5, a polar capacitor C1, a diode D1, a polar capacitor C3, a voltage-stabilizing output circuit, a trigger protection circuit, a surge current limiting circuit which is connected between the negative electrode output end of the diode rectifier U1 and the trigger protection circuit in series, and a voltage detection circuit which is connected with the voltage-stabilizing output circuit. By adoption of the automatic alternating current voltage-stabilizing power supply, the instantaneous high voltage of the input voltage can be eliminated or suppressed, so that the input voltage can be automatically stabilized within a given voltage range; and in addition, when the input voltage changes within a range of 160-260V, the output voltage can be stabilized within 220V plus or minus 2V, thereby improving the stability of the output voltage of the automatic alternating current voltage-stabilizing power supply.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an automatic AC voltage stabilized power supply with stable performance. Background technique [0002] With the continuous development of science and technology, a large number of high-tech electronic products appear in people's lives, and these high-tech electronic products also put forward higher requirements for the stability of the power supply when they are used. However, the existing power supply is prone to unstable output voltage when the mains fluctuates in a large range, resulting in abnormal use or damage of electrical equipment, which seriously affects people's lives. [0003] Therefore, it is imperative to provide a power supply capable of outputting a constant voltage. Contents of the invention [0004] The purpose of the present invention is to overcome the defect that the power supply in the prior art is prone to unstable output voltage when the commercial power fluc...
