摘要:目前,在电源系统的设计中,计算机仿真已得到广泛的应用。由于数字控制电源的控制算法等均由数字处理器编程实现,而数字处理器的工作特点决定了数据处理过程是离散化的,因此设计出能够反应数字控制系统离散化特点的仿真模型,是数字控制电源系统仿真亟待解决的问题。本文在分析数字处理器的工作特点的基础上,提出一种适合于数字控制电源系统的建模仿真方法。由于该仿真模型非常贴近于实际的数字控制电源系统,因而可以用于数字系统的原理分析和参数整定等,所获得的参数对于控制系统设计具有重要的参考价值。

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.
