摘要
介绍了一种全数字控制半导体激光器驱动电源方案。方案采用高速数字信号处理器产生高频率高分辨率的数字调制PWM直接驱动功率回路,完全采用软件实现闭环的控制,结合高精度AD采样,使得输出电流具有高精度、低纹波和高动态响应速度的特点。系统还提供六种保护功能,具有故障锁定及故障自诊断功能,具有数字化的远程通讯接口。
A real digital controlled semiconductor laser power supply system is presented. The system use a high-fre- quency ＆ high-precision digital modulation PWM which is generated by DSP to direct drive power loop, the closedloop control is completely implemented by software,with high-precision AD the output current has high-precision,low ripple and high dynamic response speed advantages. The system provides seven protections, trouble-lock and fault self- diagnosis functions,it also has a digital remote communication interface.
