Abstract

The invention relates to a laser power supply storage energy discharge system, and belongs to the technical field of a laser power supply. The discharge system comprises a power-down detection circuit, a trigger circuit and a discharge circuit, wherein the discharge circuit comprises an electronic switch tube and a depletion resistor which are connected in series, the power-down detection circuit is energized by a laser power source for detecting whether the laser power source is powered on and outputting one low-level signal when the laser power source is powered on, the control end of the electronic switch tube is arranged to at low level, the electronic switch tube is enabled to be at a closed state, the discharge circuit is disconnected, the trigger circuit is used for outputting one high-level signal when the laser power source is powered down, the control end of the electronic switch tube is arranged to be at high level, and the electronic switch tube is enabled to be at a conduction state, i.e., the discharge circuit is unlatched, such that energy in an energy storage device is discharged after the laser power source is powered down. According to the invention, the problem of the stored energy when the laser power source is powered down is solved, the laser engineering applicability and real-time performance are also quite good, and the circuit is simple and is easy to realize.

Description

technical field [0001] The invention relates to a laser power supply energy storage and discharge system, belonging to the technical field of laser power supplies. Background technique [0002] In order to instantaneously pump energy to the laser, the laser power supply needs to store energy in advance. Depending on the laser power, the stored energy is generally tens to hundreds of joules, and the voltage is between one hundred and two hundred volts. After the laser power supply is stopped and powered off, the energy accumulator will store the last charged energy, and if it is not released, it will remain in the circuit for a long time. It will adversely affect the safety of relevant staff and the life of laser power supply products. Therefore, it is very necessary to discharge the useless stored energy after the laser power supply is powered off. Contents of the invention [0003] The purpose of the present invention is to provide a laser power supply energy storage a...
