Abstract
A buck-type converter is modeled for continuos conduction mode, simulated, analysed and measured with emphasis on loop gain to be able to design for stability. As a result of this "Structured Analog Design" process, a new SPICE2 model for current-mode programming plus a useful formula for control voltage to output voltage transfer function has been derived. The theoretical background is based on Dr. R. D. Middlebrooks papers on the subject, (2,3). In a case study, both prediction and measurement show a second pole, in loop gain, at a surprisingly low frequency. This implies that the current-mode control, although it seems to be the best method for regulation, must be properly understood for avoiding oscillating units.
针对连续导通模式，建立了buck型变换器模型，并对其进行了仿真、分析和测量，重点对回路增益进行了分析和测量，以便进行稳定性设计。由于这种“结构化模拟设计”的过程，一个新的SPICE2模型的电流模式编程加上一个有用的公式控制电压输出电压传递函数已被导出。理论背景是基于Dr. R. D. Middlebrooks关于这个主题的论文，(2,3)。在一个案例研究中，预测和测量都显示了第二极，环路增益，在惊人的低频率。这意味着，虽然电流模式控制似乎是最好的调节方法，但必须正确理解以避免振荡单元。
