Abstract

The invention discloses a power supply control circuit, the power supply control circuit comprises a voltage control circuit, a current control circuit and a turn-off circuit, the input end of the voltage control circuit is connected with a laser power supply, and the voltage control end of the voltage control circuit is connected with the first control end of the turn-off circuit; the input end of the current control circuit is connected with the laser power supply, the output end of the current control circuit is connected with the input end of the turn-off circuit, and the current control end of the current control circuit is connected with the second control end of the turn-off circuit. The output end of the turn-off circuit serves as the power output end of the control circuit of the power supply and is connected with a device to be powered. By adopting the technical scheme, the problems of low reliability of the laser power supply and the like in the related technology are solved.

Description

technical field [0001] The invention relates to the field of power supply control, in particular to a control circuit of a power supply. Background technique [0002] With the increasing power of lasers, lasers have been more and more widely used in industry, laser processing and other fields, which put forward higher requirements for the reliability of power supplies. [0003] In the existing technology, the varistor on the lightning protection board is often used to stabilize and protect the power supply and power supply devices such as lasers, but the control accuracy of the lightning protection board is low, and it is difficult to stabilize and protect the power supply and power supply devices in time. In addition, the production cost of the lightning protection board is relatively high. [0004] Aiming at problems such as low reliability of the laser power supply in the related art, no effective solution has been proposed yet. Contents of the invention [0005] An e...
