资料介绍

针对现有斜坡补偿电路复杂、补偿效果不明显的现状,设计了一种用于BOOST型DC—DC变换器的斜坡补偿电路。该电路结构简单,补偿效果好,解决了峰值电流控制模式系统产生的不稳定问题,提高了开关电源的稳定性。基于VIS标准0.4μmBCD工艺实现,利用Candence软件对核心电路进行仿真。结果表明,该系统可以满足系统稳定性的要求,能稳定输出高精度电压,具有很好的应用价值。

A slope compensation circuit was designed for BOOST DC-DC converter. This circuit, which features a simple structure and high compensation effect, eliminated instability resulted from the peak current mode switching power supply system, and improved the stability of the switching power supply. The design was implemented in VIS standard 0.4 μm BCD process. Resuits from HSPICE simulation showed that the system could satisfy the requirements of the stability of the system and supply stable output voltage, which is of larger value of engineering application.
