基于无源性理论的LCL型并网逆变器无源阻尼设计以实现全频段无源输出导纳

The frequency-domain passivity theory suggests that incorporating passive output admittance in grid-connected inverters (GCIs) can effectively mitigate system instability issues. This theory has been widely recognized and applied in design guidelines for active damping (AD) and passive damping (PD) methods tailored explicitly for LCL-type GCIs. However, AD methods have a limitation in that they ca...
