Abstract

The invention discloses an automatic alternating current voltage-stabilized power supply based on a voltage detection circuit. The automatic alternating current voltage-stabilized power supply is characterized by being mainly composed of 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 constant voltage output circuit, a trigger protection circuit respectively connected with an anode output terminal and a cathode output terminal of the diode rectifier U1 and a cathode of the polar capacitor C3, and a voltage detection circuit connected with the constant voltage output circuit. The automatic alternating current voltage-stabilized power supply can eliminate or suppress the instant high voltage of an input voltage, so that the input voltage is automatically stabilized in a given voltage range; meanwhile, when the input voltage is changed in a range of 160-260V, an output voltage can be stabilized within 220+ / -2V, so that the stability of the output voltage of the automatic alternating current voltage-stabilized power supply disclosed by the invention is improved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to an automatic AC voltage stabilizing power supply based on a voltage detection circuit. 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 commerc...
