摘要
提出了ＰＷＭ开关功率变换器闭环系统分阶段数值仿真的一种方法。将主电路及控制电路作为一个统一的整体，建立闭环系统各子拓扑的线性状态微分方程，使各拓扑切换时刻的确定变得非常简单且提高了仿真效率。文中算法采用具有强大矩阵运算功能的ＭＡＴＬＡＢ语言编程实现，直接以状态方程的系数矩阵输入，实现了系统的瞬态：稳态及纹波分析的仿真，并给出了应用实例。
A stage-divided numerical simulation method for closed-loop PWM switching power converters, which establishes the system's state equations by viewing both the main circuits and the control circuits as a whole is introduced in MATLAB language. Using the coefficient matrixes of state equations as input parameters, this method can simulate the transient responses and steady-state ripples analysis of the power converters. It is shown that the simulation is efficient. A detailed description about the method is given and a typical example is presented to illustrate its applications.
