Embodiment Construction

[0027] In the present invention, a delay switch is provided in electronic equipment that requires a large starting current (such as electronic equipment with motor-like components); The switch delays starting the non-large starting current components, separates the high starting current components from the non-high starting current components, reduces the instantaneous starting current of the electronic equipment, improves the convenience of using the electronic equipment, and reduces the cost of the electronic equipment.

[0028] refer to figure 1 , a device 20 for reducing the starting current of an electronic device according to an embodiment of the present invention is proposed, which is connected to the electronic device 10; the above-mentioned electronic device 10 is provided with a power supply module 11, a large starting current module 12 and a non-large starting current module 13 (refer to figure 2 ); Above-mentioned device 20 comprises:

Abstract

The invention discloses a device for reducing starting current of electronic equipment, which is connected with the electronic equipment. The electronic equipment comprises a power-supply module, a strong starting current module and a weak starting current module. The device comprises a delay starting switching module; and the delay starting switching module is respectively connected with the power-supply module and the weak starting current module, thus the weak starting current module is later than the strong starting current module. In the device, a delay switch is utilized to delay the starting of a strong starting current component, thus the strong starting current component and a weak starting current component are started respectively, thereby reducing the instant starting current of the electronic equipment, increasing the convenience of using the electronic equipment, and reducing the cost of the electronic equipment.

Description

technical field [0001] The invention relates to the field of starting electronic equipment, in particular to a device for reducing the starting current of electronic equipment. Background technique [0002] The application of motor components in existing electronic equipment has become more and more extensive. Among them, the starting current of the motor has been greatly improved compared with before, but for electronic equipment containing multiple functional modules, the starting current is still a constraint. Important factor for device startup. [0003] For example: a hard disk is an electronic device component that uses an electric motor as a motor, and its instantaneous starting current often reaches hundreds, thousands of milliamperes (mA), or even higher. This can bring great problems to the startup of electronic devices using hard disks as storage media, especially in electronic devices connected with external mobile storage devices and handheld electronic devices...
