Suppression of electromagnetic interference in high power TEA CO2 laser system

The strong electromagnetic interference generated in high power TEA CO2 laser system mainly comes from the main discharge circuit, pulse spark switch and power supply. Such strong electromagnetic interference causes some problems such as data confusion, display frame frequency rolling and damage of power module, etc. in the high power TEA CO2 laser control sub-system. The parts in the high power TEA CO2 laser system where the strong electromagnetic interference occurs and the interference means are tested and analyzed. Adjusting the parameters of the discharge circuit to reduce the electromagnetic interference strength, adopting the patent technology of the buried coaxial high-voltage electric connector to shield the main discharge return circuit, using the PLC as the control core and shie
