复杂电力电子系统在大扰动下的稳定性是保证系统可靠运行的关键，如启动和负荷暂态等。系统级分析一般需要各模块的大信号模型。本文综述了现有的11种建立电力电子变换器大信号模型的方法，可分为三类。在此基础上，提出了一种新的基于旋转器的建模方法。与现有方法相比，该模型降低了系统阶数，适用于描述单级和级联的电流程控变换器系统。仿真和实验结果验证了该旋转器模型的可行性。本文还对这些方法进行了比较。
The stability for complex power electronics system under large disturbance is a key aspect for reliable operation, such as startup and load transient. The large signal model for each module is generally required for system level analysis. Eleven existing methods to establish large-signal models for power electronic converter are reviewed in this paper, which can be classified into three groups. Based on the review, a novel modeling method based on gyrator is proposed. Compared to the existing methods, the proposed model can reduce the system order and is suitable for describing both single and cascaded system with current programmed converters. Simulation and experimental results are presented to verify the feasibility of the gyrator model. Comparisons between these methods are also presented in this paper.
