The control algorithm requires transformations between a-b-c and d-q frames. A bridge rectifier having six IGBT power switches has been employed. For switching, compared triangular wave sinusoidal pulse width modulation (SPWM) technique has been utilized and switching frequency is adjusted to 9 kHz. Simulations are carried out with Matlab/Simulink. A major advantage of using LCL filter compared with the L filter which is the attenuation of harmonics caused by the PWM rectifier, is showed by the simulations. The feature of attenuation can be achieved only if the LCL filter properly damped, in this paper the damping process is carried out with a resistor connected series to filter capacitor. The effects of using L and LCL filter on unity power factor, line currents harmonic distortions and dc - link voltage are presented by the simulations.falseL and LCL filter | Nonlinear control | Simulation | Voltage source rectifierConference Paper2-s2.0-78651429363
