This paper presents a comparison between two different passive filters for power converters tied to the grid with the application of active power injection. It addresses the L (inductive) filter and the LCL (inductive-capacitive-inductive) filter in single-phase power converters for which are presented the parameter design and modeling. These filters provide coupling of the power converter to the...
This paper presents the modeling and control design of a single-phase full bridge neutral point clamped (FB-NPC) multilevel converter used in an active power filter (APF) application. The proposed topology is aimed to compensate reactive power and current harmonic distortion. Based on the system model, a multi-loop controller is proposed, which is aimed to accomplish three control objectives, namely,...
