Abstract
The power supply' s performance is very important for the stability of laser diode (LD) output. So according to the request, a feasible system about the digital power based on TMS320F2812 DSP is demonstrated. Making use of the DSP, the PID arithmetic is adopted, and one table for the feedback control is also built. The pulse current amplitude, pulse width and the pulse frequency can be modified. Many experiences show that this system is steady and reliable in the course of practical application.关键词
