Control of LCL Filter Based Voltage Source Converter


14th International Power Electronics and Motion Control Conference (EPE-PEMC), Ohrid, Makedonya, 6 - 08 Eylül 2010 identifier identifier


In this paper, the control of Voltage source converter which consists of six IGBT power switches is realized. Grid connection of VSC is provided through LCL filter and sinusoidal pulse width modulation (SPWM) technique which has 9 kHz switching frequency, is used for switching. Three different way of control including a - b - c, d - q and input - output linearization nonlinear control, are analyzed and achieved with simulations in Matlab/Simulink. The effects of control methods to the grid and dc - link are examined.
