Comparison of power control method for B4 converter connected to unbalanced grid
Autor: Simek P.; Valouch V.
(Czechoslovakia Section IEEE, 2020)The aim of the paper is to present a power control of a three-phase inverter with only four inverter legs (connections B4) connected to an unbalanced grid. The results obtained by the predictive power control with a finite ... -
Comparison of predictive direct power control methods for grid-connected converter in B4 configuration
Autor: Valouch V.; Simek P.
(Technical University of Košice, 2019)A model predictive direct power control of the three-phase converter with only four converter branches (B4) connected to an unbalanced grid is introduced. The developed infinite-control-set and usual finite-control-set MP ... -
Experimental investigation of fault tolerant converter connected to unbalanced grid
Autor: Valouch V.; Simek P.; Skramlik J.
(Czech Section of the IEEE VUT, 2018)A model of the three-phase voltage converter for simulation of its modes of operation in standard as well as fault states is presented The presented model can be used to simulate steady-states and also transients at dc and ... -
A frequency locked loop strategy for synchronization of inverters used in distributed energy sources
Autor: Šimek P.; Škramlík J.; Valouch V.
(Elsevier Ltd, 2019)A technique has been developed that incorporates the advantages of the cascaded delayed signal cancellation and dual second order generalized integrator schemes, the first one being used now as a pre-filter for the second ... -
Generalized predictive power control for grid-connected converter
Autor: Simek P.; Valouch V.
(Elsevier Ltd, 2021)The aim of the contribution is to present a new method for the control of the active and non-active instantaneous power for the grid-connected voltage source converter. The GPPC (Generalized Predictive Power Control) is ... -
Model Predictive Direct Power Control of Four-Switch-Based Inverter Connected to Unbalanced Grid System
Autor: Čerňan M.; Müller M.; Müller Z.; Tlustý J.; Valouch V.
(IEEE, 2018)A model based predictive direct power control with finite set of control variables for the three phase four-switch-based converter B4 connected to an unbalanced grid is introduced. The instantaneous active and non-active ... -
