The invention relates to a high-voltage receiving control device for high-power CO2 (carbon dioxide) lasers. The high-voltage receiving control device comprises a constant-rate power supply, an optical receiver, a DAC (digital-to-analog converter), an analog switch, an operational amplifier module and a power amplifier; the constant-rate power supply is used for converting external alternating current into direct current and powering the optical receiver, the DAC, the optional amplifier module, the analog switch and the power amplifier; the optical receiver is used for receiving external optical signals and converting the same into digital signals to be sent to the DAC; the DAC is used for converting the digital signals serially inputted into analog current output signals to be outputted to the analog switch. The high-voltage receiving control device is simple in structure, convenient to operate, low in consumption power, low in operation cost and capable of being used in multiple complex environments.
Description
technical field [0001] The invention relates to a CO2 high-voltage receiving control device for high-power lasers, which is suitable for the fields of laser cutting machines and the like. Background technique [0002] High-power CO2 laser is a relatively complex industrial equipment. It not only has a high-voltage, high-current power supply and a vacuum cavity with multiple sealing surfaces, but also must maintain the dynamic stability of the working gas composition and pressure, and at the same time generate a large amount of energy during operation. The heat needs to be cooled and is also sensitive to temperature changes. [0003] The existing laser receiving control circuit adopts the optocoupler isolation method, which converts the optical signal into an electrical signal and then amplifies the digital signal, which will lead to poor anti-interference ability, and cannot give stable voltage and current to the high-power CO2 laser. The normal and stable operation of the ...
