基于SABER軟件的數字控制電源系統的仿真設計

摘要：目前，在電源系統的設計中，計算機仿真已得到廣泛的應用。由于數字控制電源的控制算法等均由數字處理器編程實現，而數字處理器的工作特點決定了數據處理過程是離散化的，因此設計出能夠反應數字控制系統離散化特點的仿真模型，是數字控制電源系統仿真亟待解決的問題。本文在分析數字處理器的工作特點的基礎上，提出一種適合于數字控制電源系統的建模仿真方法。由于該仿真模型非常貼近于實際的數字控制電源系統，因而可以用于數字系統的原理分析和參數整定等，所獲得的參數對于控制系統設計具有重要的參考價值。 敘詞：數字控制，電源，仿真，建模 Abstract：Computer simulation has been widely used in design of power supply systems presently. In the system of digital controlled power supply, control scheme is programmed in digital processor. The character of processor decides that the process of datum disposal is discrete. Therefore, its a problem for simulation of digital controlled power supply systems to establish simulation models which can reflect discrete feature. This paper offers a method of modeling and simulating for digital controlled power supply system, on the basis of analyzing the feature of how datum are processed in digital processor. Because this simulated model approximates to the practical digital controlled power supply system greatly, it can be used to principle analyzing, more importantly it can be used to parameter trimming in digital control system, and the final simulated datum will be referred to the practical digital controlled system importantly.
