| Abstract: | The spectral test system demands for the stability of the light source increasingly.A tungsten lamp power supply whose light source is stable,which is controlled by a single chip microcomputer is introduced.With C8051F410 single chip microcomputer as the core,it uses control algorithm of incremental PID,and through controlling the D/A converter of the single chip microcomputer to adjust the MOS FET working state to stable the current of the tungsten lamp.It assures that the tungsten lamp radiates steadily.E... |
