Abstract

The invention discloses a soft start and current stabilization circuit based on a voltage adjustment circuit, which is characterized in that: it mainly consists of a transformer T, a diode rectifier U, a triode VT4, a capacitor C1, a capacitor C4, a capacitor C5, a capacitor C6, a resistor R6, and a resistor R7 , Resistor R8, soft start circuit, voltage adjustment circuit and delay circuit. The present invention can realize the soft start of the electronic product, so that the output voltage of the present invention will rise to a given value at a slower speed through a start-up process after the power is turned on, so as to protect the electronic product from the impact of the surge when starting ; When starting, the present invention can also guarantee the optimal delay time of about 30 seconds; it is suitable for popularization and application.

Description

technical field [0001] The invention relates to a soft start circuit, in particular to a soft start current stabilization circuit based on a voltage adjustment circuit. Background technique [0002] With the development of science and technology, electronic technology has developed rapidly, and the types of electronic products have become more and more abundant. Various electronic products have entered the families of ordinary people, making people's daily life inseparable from electronic products. Because the performance of various electronic products is not the same, some electronic products need soft start when they are used, so as to protect the electronic products from the impact of surge when they are started. However, the current structure for realizing soft start is relatively complicated, and the delay time for starting is relatively long, which brings great inconvenience to users. Contents of the invention [0003] The purpose of the present invention is to prov...
