Summary:

The driving power system can be combined with lasers, lights, et cetera, and applied to automobiles to achieve various functions. Under the general trend of the development of intelligent vehicles, people have higher and higher requirements for the accuracy and power of various equipment. However, as power increases, how to ensure the stability of factors such as current is a challenging problem. Therefore, it is extremely important to study and design a high-power drive system in this paper, so as to ensure a stable output of the current. The system is composed of power supply, load, secondary power supply and control chip. The choice of power supply and load is conventional model. The secondary power supply adopts step-down circuit, with synchronous rectifier chip, which can effectively reduce energy consumption, and with temperature protection device, which can ensure the safe and reliable operation of equipment. The control part adopts the algorithm of combination of incremental PID and integral separated PID, and the accurate output of current can be realized by adjusting duty cycle. The results show that the linearity is only 0.82%, the return error tends to zero, and the maximum accuracy error is 0.02A, which basically meets the requirements. Compared with other research achievements, the content in this paper has a certain integrity, and has high practicality in laser, lighting and other equipment
