Abstract

The invention discloses an amplifying and filtering type surge current limiting circuit based soft start-up current stabilization circuit which comprises 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, a resistor R7, a resistor R8, a soft start-up circuit, a surge current limiting circuit, an amplifying and filtering circuit and a delay circuit. The circuit of the invention can realize the soft start-up of an electronic product. When electrically connected, the voltage is gradually outputted at a relatively slow speed to reach a give amount so that the electronic product is free from the impact of surge during the start-up process. In start-up, the circuit of the invention can also ensure a best delay time of around 30 seconds. The circuit can be widely utilized.

Description

technical field [0001] The invention relates to a soft start circuit, in particular to a soft start current stabilization circuit based on an amplifying and filtering surge current limiting 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 th...
