Switched DC Sources Inverterbased Shunt Active Power Filter for Power Quality Improvement

A simple and reliable inverter is a prerequisite for realizing an efficient active power filter. This paper presents a reduced switch count (RSC) based asymmetrical switched dc sources inverterfor a threephase three-wire (3P3W)shunt active power filter (SAPF). The performance of considered RSCtopology is studied on seven-level asymmetrical configuration with simple level-shifted pulsewidth modu...

A shunt active power filter control for unbalanced conditions

This paper first presents a simple control technique for active filters to compensate current harmonics and reactive power of nonlinear loads. This method is usable for both single –phase and three –phase systems. Then a new method for load balancing and reactive power compensation for unbalanced sinusoidal load currents is presented. Finally by combination of two methods an active filter contr...

Active Filter Control Method Based on Direct Power Control for Compensating Reactive Powers due to Unbalanced Voltages and Nonlinear Loads

Active filters have proven to be more effective than passive techniques to improve power quality and to solve harmonic and power factor problems due to nonlinear loads. This paper proposes a control scheme based on the instantaneous active and reactive power. The inverter of this active filter is a three-phase, two-level converter. Space vector technique is used as modulators and pattern genera...

A Review of Multilevel Inverter Based Active Power Filter

Use of nonlinear loads at high voltages has increased tremendously in industry. These non-linear loads distort power quality by generating harmonics. Conventional active filters have limitations in high power high voltage systems. Use of multilevel inverter in active filters effectively reduces harmonics in high voltage systems eliminating need of high cost and bulky transformer. This paper pre...
