论文摘要
本文研究了一种新方法，以在开关同步采样状态空间中建模和控制可变频率转换器，以进行循环数字控制。与其他方法相比，包括快速动态性能以及易于设计和实施的其他方法，有许多重要的好处。通过硬件呈现和验证理论结果，并对具有恒定按时的电流模式倒数转换器和具有恒定暂时的电流模式增强转换器进行仿真。微处理器和激光雷达的动态电压缩放是可以受益的应用。
This paper investigates a new method to model and control variable-frequency power converters in a switching-synchronized sampled-state space for cycle-by-cycle digital control. There are a number of significant benefits in comparison to other methods including fast dynamic performance together with ease of design and implementation. Theoretical results are presented and verified through hardware, and simulations of a current-mode buck converter with constant on-time and a current-mode boost converter with constant off-time. Dynamic voltage scaling for microprocessors and LiDAR are among the applications that can benefit.
