The controller itself is error-free, temperature drift of the device are 100PPM, the target can be achieved. The display accuracy refers to the panel displays the current and final output current error, a feedback link in a chain. The earlier analysis of the accuracy of the feedback loops of 1 percent display accuracy of the feedback link in a chain. This indicator is also achievable. This chapter first introduces the introduced krypton lamp and its power system characteristics. Followed by a demonstration of the system program, and a detailed summary of the middle and end of the argument. The above arguments show that the laser power to be developed is feasible in theory. In the process of argumentation, but also the selection of the main devices. As the laser technology of the green laser pointer becomes more and more advanced and mature.
DSP digital hardware of the laser power of the overall block diagram in Figure 3 1. The all-digital laser power is divided into five modules - the main circuit board, pre-combustion board, the master analog board, DSP control board and control panel. The functions of each module are as follows: the main circuit board 220V AC input, rectifier, filter, chopper, the output filter to the final output. Precombustion board to produce the high-voltage lighting, high voltage freewheeling; master analog board is mainly responsible for the DSP board and the other signal isolation circuit to improve circuit reliability and anti-jamming capability; DSP board is the core of the control of the entire system responsible for controlling the control panel, the main circuit PCB board to provide various control signals and receive feedback and protection of the signal, and DA board serial communications. The performance and function of the green laser pointer are becoming more and more perfect and complete. 
This section introduces the main circuit and control circuit design and implementation process. The main circuit is the control object, the control circuit is the feedback part of the system. A detailed description of the main circuit and control circuit, in fact, the basic description of the complete circuit of the control system. After the completion of the main circuit and control circuit, the hardware portion of the control system has been basically completed.
