Stability Analysis of 2H Bridge Cascaded Three-level Single-phase Inverter Based on Nonlinear Dynamics

通过分岔图、折叠图、雅可比矩阵等非线性动力学方法,分析2H桥级联式三电平单相逆变器的稳定性,得到逆变器系统随相关参数变化的稳定范围,为逆变器的设计和调试提供指导和借鉴。

The stability of 2 H bridge cascade three-level single-phase inverter is analyzed by nonlinear dynamics methods such as bifurcation diagram, folding diagram and Jacobian matrix, and the stability range of the inverter system with the change of relevant parameters is obtained, which provides guidance and reference for the design and debugging of the inverter.
