摘要: Compared to L-type filter, LCL-type filter have resonance frequency point, consequently reduce the reliability of VSC converter. The general control strategy with passive damping or active can improve stability converter, but it will bring extra loss, and need more sensors. This paper compare analysis performance LCL converter controller different feedback variables. Based on optimization choice variable, a novel notch concept is proposed. design method parameter also simulation experimental results verifies system design.
