- The driving power system can be combined with lasers, lights, etc., 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. 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 a certain value of current. The system is composed of power supply, load, secondary power supply and control chip. The secondary power supply adopts BUCK type circuit and cooperates with synchronous rectifier chip. The control part uses two PID control algorithms. After the MATLAB and Multism simulations, the experimental part is expanded, and the results show that the linearity is only 0.82%, the return error tends to zero, and the maximum accuracy error is 0.02V, which basically meets the requirements and has a certain practicability.
