摘要
本文通过介绍电流模式PWM升压变换器的工作原理,分析了斜率补偿对于大信号稳定的必要性,提出了斜率补偿电路的实现方法,使得补偿斜率与输出电压和输入电压的差值成正比,并给出了斜率补偿电路的hspice仿真结果。
The paper introduces the general function of current mode control PWM converter＇s theory, analyzes slope compensation＇s necessity for system＇s large signal stability, proposes a slope compensation circuit in which the compensation slope varies with the difference value of output voltage and input voltage. At last the paper gives the simulation results of the circuit design with Hspice.
