Design of Multifrequency Proportional–Resonant Current Controllers for Voltage-Source Converters
IEEE transactions on power electronics, 2020In recent years, the applicability of multifrequency proportional–resonant (PR) current controllers has been extensively explored. The analysis and controller design are typically performed by means of frequency response methods.

Controllers for voltage source converters
2013 International Conference on Emerging Trends in Communication, Control, Signal Processing and Computing Applications (C2SPCA), 2013The power system is dependent on control of power and voltage for its stability and reliability. Voltage Source Converter (VSC) technology has the advantage of being able to almost instantly change its working point within its capability limit. Due to this advantage, VSC can be used to support the system to maintain active power or output voltage ...

SISO Transfer Functions for Stability Analysis of Grid-Connected Voltage-Source Converters
2018 International Power Electronics Conference (IPEC-Niigata 2018 -ECCE Asia), 2019Converter–grid interaction is of great interest in a weak-grid condition. In this paper, an alternative multi-input multi-output closed-loop system is developed for the stability analysis of grid-connected voltage-source converters.

Stability Analysis of Grid-Connected Voltage-Source Converters Using SISO Modeling
IEEE transactions on power electronics, 2019The interaction of a grid-connected voltage-source converter with a weak grid is of significant interest. In this paper, the converter together with the grid impedance is modeled as a single-input single-output (SISO) system.

Exact Modeling of the Voltage Source Converter
IEEE Power Engineering Review, 2001A discrete time, linear time varying model of the three-phase voltage source converter (VSC) is developed. The model is employed to determine the steady state operating characteristics of a VSC taking all ac-dc side harmonic interactions into account. The procedure is based on an exact closed form solution of the system equations and does not rely on ...

Derivation of multilevel voltage source converter topologies
IECON 2016 - 42nd Annual Conference of the IEEE Industrial Electronics Society, 2016Multilevel converters have gained popularity in both medium voltage and low voltage applications. To find out the connections between various multilevel voltage source converter topologies and reveal how to obtain new topologies, this paper has presented four methods to derive multilevel converter topologies.
