Comparison of current control techniques for active filter applications

This paper presents the comparative evaluation of the performance of three state-of-the-art current control techniques for active filters. The linear rotating frame current controller, the fixed-frequency hysteresis controller, and the digital deadbeat controller are considered. The main control innovations, determined by industrial applications, are presented, suitable criteria for the compari...

Comparison of Current Control Strategies for Three- level Four-leg Shunt Active Power Filter

This paper presents a comparison of two control strategies for 3-level 4-leg Shunt Active Power Filter (SAPF). The first method is based on hysteresis controllers. The second, proposed method is the Model Predictive Control (MPC) with a finite control-states set (FS) based on phase-to-phase model. The two methods are described and simulation results are presented and analyzed. Comparison is per...

Hysteresis Control for Current Harmonics Suppression Using Shunt Active Filter

Recently wide spread of power electronic equipment has caused an increase of the harmonic disturbances in the power systems. The nonlinear loads draw harmonic and reactive power components of current from ac mains. Current harmonics generated by nonlinear loads such as adjustable speed drives, static power supplies and UPS. Thus a perfect compensator is required to avoid the consequences due to...

The Comparison Study of Current Control Techniques for Active Power Filters

This paper presents the comparison study of current control techniques for shunt active power filter. The hysteresis current control, the delta modulation control and the carrier-based PWM control are considered in the paper. The synchronous detection method is used to calculate the reference currents for shunt active power filter. The simulation results show that the carrier-based PWM control ...
