The Shunt Active Power Filter is a very essential tool to remove harmonic currents and to reimburse reactive power for nonlinear loads. The fundamental standard of process of a Shunt Active Power Filter is to introduce an appropriate non-sinusoidal current (compensating current) into the system at the point of common coupling. This research work focuses on the time-domain approach for three-pha...

The paper presents a three-dimensional space-vector-modulation scheme for three-phase four-wire active power filters. The focus is on the implementation of a fixed frequency pulse width modulation (PWM) scheme with a minimum number of switch commutations per period and maximum DC bus voltage utilisation. For three-wire applications, space vector modulation is known to provide better utilisation...

Abstract— Reduction of the Harmonics is one of the major needs for Power System & it is demanded that source should provide a balanced & pure sinusoidal three-phase voltage of constant amplitude to the loads. But, due to excessive use of Power Electronics, a complex power quality problem evolved characterized by the voltage and current harmonics. Active power filters have been developed to solv...

This paper demonstrates an enhancement of power quality in grid integrated systems with the help of the proposed control strategy for voltage source converter based active power filters. The Shunt Active Power filters (SAPF) are extensively utilized in modern grid integrated systems to diminish the power quality concerns associated with it. The SAPF is one of the various power filters, which ha...
