The middle capacitor voltage of an LCL-filter, if fed back for synchronization, can be used for
active damping. An extra sensor for measuring the capacitor current is then avoided …

Grid-connected converters (GcCs) employ LCL filters instead of simple L filters in order to
meet new grid codes and their on-going changes in the near future. Active damping …

This paper presents the development of a discrete-time Robust Adaptive One Sample
Ahead Preview controller, based on the combination of a Robust Model Reference Adaptive …

Recent technical advances in control, protection and interconnection of distributed power
generation units imply that it is practically viable and economically profitable to keep them as …

Although switched-capacitor (SC) multilevel inverters (MLIs) offer self-voltage balancing of
flying capacitors and voltage gain higher than unity, the advantages come at the cost of high …

This paper presents a variable structure control in natural frame for a three-phase gird-
connected voltage-source inverter with LCL filter. The proposed control method is based on …

In this paper, a robust grid-current-feedback resonance suppression (GCFRS) method for
LCL-type grid-connected inverters is proposed to enhance system damping without …

Active damping is a popular approach to suppress the resonance in LCL-filtered grid-
connected inverter owing to lossless damping and efficient system design. In capacitor …

The conversion and utilisation of renewable energy generations often require grid‐
connected inverters. When applying LCL filter to remove power electronic chopping …

This paper investigates the stability of LCL-fil-tered grid-connected inverters with capacitor
current feedback (CCF) active damping. The impact of time delays in the digital controller on …
