摘要

本文介绍了一种用于峰值电流型升压DC-DC变换器的斜率补偿电路的设计。该电路结构简单，消除了双环控制产生的峰值电流型系统的不稳定性问题。避免了由于补偿不当造成的瞬态响应慢、承载能力低等不利影响。提高了开关电源的稳定性。该设计基于台积电0.35 μm CMOS工艺实现。频谱仿真结果表明，当感应电流发生扰动时，系统不会发生长时间振荡，能提供稳定的输出电压。

Design of a novel nonlinear slope compensation circuit for peak current-mode boost DC-DC converter

This paper introduces a design of slope compensation circuit for peak-current-mode boost DC-DC converter. The circuit is simple, and eliminates instability problem of the peak-current-mode system generated by double-loop control. And it avoided detrimental effects on account of improper compensation, such as slow transient response, low carrying capacity. It improves the stability of the switching power supply. The design is implemented base on the TSMC's 0.35 μm CMOS process. The spectre simulation results show that, when the inductive current occurs disturbance, the system do not occur prolonged oscillation, can supply stable output voltage.
