Abstract

The invention discloses a regulating circuit, which comprises a control module, a delay module and an electronic switch, wherein the control module is connected with power supply equipment and electric equipment, and is used for outputting a signal; the delay module is connected with the control module and the electronic switch respectively, and is used for adjusting the intensity of the signal received by the electronic switch to change the switch-on speed of the electronic switch; the first end of the electronic switch is connected with the control module and the delay module respectively; the second end of the electronic switch is connected with the power supply equipment; the third end of the electronic switch is connected with the electric equipment. By adopting the regulating circuit, the switch-on speed of the electronic switch can be controlled through the delay module and the control module, so that the aim of the regulating the surge current is fulfilled.

Description

technical field [0001] The invention relates to a surge current regulating circuit. Background technique [0002] Electronic products will generate inrush current at the moment when they are powered on, and the faster the opening speed of the electronic switch used to connect the power supply equipment and electronic equipment, the greater the inrush current value will be. The surge current has a great impact on the reliability of the entire system, and even causes the system to stop working due to overcurrent protection. However, the current design of the surge current cannot adjust the magnitude of the surge current. devices have some limitations. Contents of the invention [0003] In view of this, it is necessary to provide an adjustment circuit that can adjust the magnitude of the surge current. [0004] A surge current regulation circuit, comprising: [0005] A control module, connected between a power supply device and a power consumption device, when the power su...
