Design of Boost Topology Constant Current Output Control Based on FPGA
The traditional Boost topology has certain limitations in terms of output voltage stability,especially in terms of response speed and stability when load changes occur.To address this issue,this paper proposes a Boost topology constant current output con-trol method based on Field Programmable Gate Array(FPGA).Firstly,a detailed analysis is conducted on the topology structure and working principle of the Boost topology to reveal its control requirements and challenges.Secondly,using FPGA to collect real-time parameters such as input voltage,output voltage,and output current,and comparing and calculating feedback signals through a com-parator,closed-loop control of Boost topology output current is achieved.Finally,the effectiveness and performance advantages of the proposed method are verified through experiments.The experimental results show that the FPGA based constant current output control method has good dynamic response characteristics and stability performance,and can quickly adjust the output current when dealing with load changes,achieving efficient and stable power output.This study is of great significance for improving the control performance of Boost topology circuits and promoting technological progress in the field of power electronics.
