Abstract

An adaptive slope compensation circuit applied to buck DC-DC converters is presented in this paper. Based on the basic theory of slope compensation, the conditional expression of the loop stability is gained. According to the conditional expression, using feed-forward control of the input voltage and the feed-back control of the output voltage, the slope compensation is provided with adaptivity, which makes the system stable with the variation of duty cycle all the time. In addition, the proposed slope compensation circuit improves the system's loading capacity and transient response in high duty cycle. The circuit is designed on the base of Samsung BCH4 process, and its performances have been verified by Hspice simulation.
降压DC-DC变换器的自适应斜率补偿电路
提出了一种适用于降压型DC-DC变换器的自适应斜率补偿电路。根据斜率补偿的基本理论,得到了回路稳定性的条件表达式。根据条件表达式,采用输入电压的前馈控制和输出电压的反馈控制,使斜率补偿具有自适应性,使系统随占空比的变化始终保持稳定。此外,所提出的斜率补偿电路提高了系统的负载能力和高占空比的暂态响应。该电路基于三星BCH4工艺设计,并通过Hspice仿真验证了其性能。
