| Abstract: | A design of fiber lasers power control system is presented with MC9S12XDP512 as the core control combined with peripheral circuits.The resistance of the single-chip microcomputer controls digital potentiometer DS1867 is used to change the switching power supply voltage of the control port,thus realizing the control of power supply current of a fiber laser.The voltage-controlled switch current source PCO-6131 is adopted to change fiber laser output power.The system can also detect the environment temperature with high-temperature alarm and timer control.Test results show that in the application of fiber laser in the marking,stable power output is obtained with temperature detection function,and the whole system is stable and reliable. |
