考虑PWM饱和的并网逆变器频闪映射建模与分岔特性研究

For the grid-connected inverter system, the sustained constant-amplitude oscillations often occur. At this time, the grid-connected current undergoes oscillation, and the PWM process appears saturation nonlinearity (i.e., overmodulation). However, the existing modeling methods cannot accurately model this hard nonlinearity, thereby explaining the phenomenon of grid-connected current oscillation. I...
