Abstract

The invention discloses a soft starting current stabilization circuit based on a voltage regulation type surge current limiting circuit. The soft starting current stabilization circuit is characterized by mainly comprising 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 startingcircuit, a source constant current driving circuit, a surge current limiting circuit, a voltage regulation circuit and a time delay circuit. The soft starting current stabilization circuit can realizesoft starting of an electronic product, and output voltage is enabled to pass through a starting process and ascend to a given value at a relatively low speed after the soft starting current stabilization circuit is connected to a power supply, so that the electronic product is prevented from being impacted by the surge when being started; the soft starting current stabilization circuit can alsoensure the optimal delay time of about 30s during starting; and the soft starting current stabilization circuit 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-adjustable 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 the prese...
