IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the

A voltage-source inverter for microgrid applications with an inner current control loop and an outer voltage control loop [PDF]
, 2009 Distributed generation (DG) units are commonly inter-faced to the grid by using voltage-source inverters (VSI’s). Extension of the control of these inverters allows to improve the power quality if the main power grid is disturbed or disconnected. In this

A Novel Sliding Mode Control Strategy for VSG‐Based Inverters with Disturbance Estimation
IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.To enhance the robustness of the VSG‐based inverter control system against uncertain disturbances, this paper proposes a novel sliding mode control strategy consisting of two control layers for VSG‐based inverters based on disturbance estimation. ABSTRACT The interface inverter control system based on virtual synchronous generator (VSG) technology, has

Ripple‐Free Input Current Quadratic Converter Based on Watkin–Johnson Topology
IET Power Electronics, Volume 18, Issue 1, January/December 2025.This article proposes a power electronics converter capable of providing high voltage gain while keeping a high‐quality input current ripple. The technique for achieving the zero input current ripple at a selected duty cycle consists of extracting two inductor currents from the source in a counter‐phase manner.

Low-Voltage Ride-Through Coordinated Control for PMSG Wind Turbines Using De-Loaded Operation
IEEE Access, 2021 Low-voltage ride-through (LVRT) is important for the grid integration of wind power systems (WPSs). Each grid operator defines a grid code, including the LVRT requirement, considering their power system characteristics. During grid faults, LVRT is needed
