摘要
为薄板焊接而专门研制的精密CO_2激光焊机，其电源采用带集成触发的三相晶闸管调压主电路，通过深度电流负反馈获得垂直陡降的电源外特性，由计算机对电源进行控制，实现激光功率输出的精密自动调节。
A kind of precise CO_2 laser welder has been developed specially for welding of thin plates.The laser power supply employs three-phase SCR voltage-regulating main circuit with IC triggering circuit.Its V- I characteristic curve with perpendicularly steep drop is obtained through deep current negnectfeedback to the main circuit. circuit power output can be adjusted precisely and automatically throughcomputer-controlling to the power supply.
