摘要
Abstract
As a low-loss,efficient and reliable power supply device,switching power supply is widely used in industrial pro-duction,electronic equipment and daily life.In view of the fact that the performance of the traditional PI-controlled full-bridge pow-er electronic DC-DC converter can not meet the needs of adaptive change in practical applications,this paper introduces the main topologies of several current mainstream DC-DC converters and analyzes their performance in the system.Then,the operation pro-cess of phase-shifted full-bridge DC-DC converter is introduced,the shortcomings of traditional PI control method are analyzed,and a closed-loop adaptive fuzzy PI control method is proposed,which is characterized by dynamically adjusting PI parameters ac-cording to different working conditions,and the intelligent control of phase-shifted full-bridge DC-DC converter is realized.The simulation results in Matlab/Simulink show that the dynamic performance of fuzzy PI control mode is better than that of traditional PI control mode when the load changes suddenly and the output voltage changes.At the same time,the ripple coefficient of the output voltage is greatly reduced and the accuracy of the output voltage is improved.关键词
