    Control of LCL filter based Voltage source converter
    (2010-12-27) Şehirli E., Altinay M.
    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. © 2010 IEEE.

    Simulation of three-phase voltage source pulse width modulated (PWM) LCL filtered rectifier based on input-output linearization nonlinear control
    (2010-08-24) Şehirli E., Altinay M.; Sehirli, E, Altinay, M
    Control of three - phase voltage source pulse width modulation (PWM) LCL filtered rectifier based on input - output linearization nonlinear control is realized. This control algorithm needs to transformation between a - b - c and d - q coordinates. In this paper, grid connection of rectifier which consists of six IGBT power switches, is provided through LCL filter and sinusoidal pulse width modulation (SPWM) technique which has 9 kHz switching frequency, is used for switching. All simulations are carried out with Matlab/Simulink. By the simulation results, line currents' harmonic distortions, and dc - link voltage and the obtaining of unity power factor are shown under load and reference changes. ©2010 IEEE.
