基于改进变分模态分解与小波变换的DC-DC变换器共存吸引子识别及动力学特性量化

As a nonlinear system, the dc–dc converter exhibits nonlinear behaviors, such as bifurcation, chaos, and coexisting attractors, which greatly reduces its reliability. Therefore, predicting and identifying these nonlinear behaviors is of great significance to the application of dc–dc converter. And many effective methods have been proposed for identifying nonlinear behaviors. However, the tradition...
