Buck-Boost变换器电流滞环控制策略的研究与改进
Study and Improvement of Hysteresis Current Controlled Buck-Boost Converter
摘要
Abstract
Although the hysteresis current control strategy possesses high stable precision and fast response speed , its transient performance is not very ideal if the load changes. To reduce the dynamic response time and improve the load regulation,a modification based on hysteresis current control strategy is proposed,which is called transient hys⁃teresis current control strategy. It follows the principle of charge balance. Also the theory is analyzed and the mathe⁃matical model is made in detail. A Buck-Boost prototype is designed based on STM32F407VGT6 development board. The results show that adopting the improved hysteresis current control strategy,the load regulation is increased about 1%and the dynamic response time is shorted about 200μs when the load changes.关键词
