摘要

本文旨在对DC-DC变换器的各种数字控制方法进行比较研究。这些控制方法使用数字电位器、数字模拟转换器或滤波后的DPWM信号连接在DC-DC转换器的反馈控制回路中，以调节转换器的输出电压。综合提出了不同的数学模型，用于计算每种类型的控制的最佳分量值，详细说明了在转换器的整个输出范围内分量值变化的最常见影响。计算机辅助模拟和一系列实验测量的结果验证了之前提出的每个数学模型。总之，这些控制方法的比较对实际应用中的线性度、分辨率、编码效率等方面提供了一些实用的建议。

Practical synthesis of various control methods for digitally adjusted DC-DC converters

This paper aims to present a comparative study of various digital control methods for DC-DC converters. These control methods uses Digital Potentiometers, Digital Analog Converters or filtered DPWM signals connected in the feedback control loop of a DC-DC converter in order to adjust the output voltage of the converter. The synthesis presents different mathematical models for calculating the optimal component values for each type of control, detailing the most common effects of components value variation over the entire output range of the converter. The results from computer-aided simulations and a series of experimental measurements validate each previously presented mathematical model. In conclusion, the control methods comparison offers some practical advises about the linearity, resolution, code efficiency in real applications.
