LCL Filter Design for Interconnection Inverter of Distributed Source to Utility Grids
 Valouch, Viktor ; Bejvl, Martin
Properties and behavior of the LCL grid filter for PWM converters in terms of grid current harmonic spectra and filter operation conditions are analyzed in the paper. A procedure to determine filter parameters and also the comparison of the filter performance criteria provided by developed programs is presented.

High Power PWM rectifiers
 Valouch, Viktor ; Šimek, Petr ; Škramlík, Jiří
High power, high voltage PWM rectifiers with low swirching frequency are analyzed in terms of attainable powers exchangedwith the grid and of their current frequency spectra. Four-level PWM rectifiers with rated powers S = 2, 4, 8 MVA and the switching frequency 800 Hz per one switching element are considered, thus the controlller sampling frequency 1600 Hz is used. Selected results of simulation as wellas experimental tests are presented.
