Abstract

The invention relates to a method for realizing a double-path laser power supply high-voltage isolation device, which comprises a high-voltage sampling circuit and a current feedback amplifier circuit, and has the advantages that: a non-contact Hall current sensor LA50-P samples the high-voltage current of a laser power supply; the reliable and effective sampling of the high-current (10A) Hall current sensor to low current (mA) is realized successfully, and signals are processed; the high-voltage isolation between the output and the input of the laser power supply is effectively realized; and the problem that a traditional carbon dioxide (CO2) laser power supply cannot be applied to a power supply system in which a plurality of laser tubes are serially connected and the like because the low potential points of a high-voltage output end are connected with a case (i.e. the ground) is fully solved.

Description

technical field [0001] The invention adopts the non-contact Hall current sensor to sample and feedback the high-voltage output current, and realizes the complete isolation of the high-voltage output of the laser power supply, so as to meet the requirements of the CO with special requirements. 2 The laser tube is powered. Background technique [0002] Currently CO 2 The rapid development of laser, especially the laser tube below 150W has basically solved the problems of its corresponding technology, and the technology is gradually becoming mature. But for CO above 150W 2 As far as laser tubes are concerned, its manufacture, especially whether it can meet the needs of long-term stable operation, is still a problem that plagues the industry. [0003] The traditional laser tube manufacturing technology mainly uses methods such as increasing the length and diameter of the glass tube to increase the output power of the laser tube, but due to the stress characteristics of the gl...
