Experimental validation of an adaptive control for a Voltage Source Converter

2013 American Control Conference, 2013
In this work an adaptive controller is designed to provide reactive power compensation and dc voltage tracking of a three phase Voltage Source Converter (VSC). The method relies on a third order model of the VSC which accounts for uncertainty in three system parameters.

Catastrophic Bifurcation in Three-Phase Voltage-Source Converters

IEEE Transactions on Circuits and Systems I: Regular Papers, 2011
Active pulse-width-modulated (PWM) voltage rectifiers are commonly used to convert ac power from a three-phase grid to a regulated dc voltage with unity input power factor. The output voltage regulation is normally achieved by an outer voltage feedback loop and a sinusoidal pulse-width-modulated (SPWM) inner current loop.

Discrete-Time Voltage Controller for Voltage Source Converters With LC Filter Based on State-Space Models

IEEE transactions on industry applications, 2019
State-space control could provide both high dynamic performance and sufficient stability margin to voltage source converters with LC filter. However, an inherent digital delay induced by a digital control system deteriorates performance and even induces ...

Current Regulation in Four-Leg Voltage-Source Converters

IEEE Transactions on Industrial Electronics, 2007
Three-phase four-leg voltage-source converters by virtue of the fourth leg connected to the neutral points of the wye-connected loads effectively handle the zero-sequence currents and voltages occasioned by connected load impedance imbalances and/or nonlinearity of loads.
