Design and Simulation of Split-Capacitor Based Three-Phase Four-Wire Shunt Active Power Filter

This paper emphasis on design parameter and performance analysis of Split-Capacitor based Three-Phase Four-Wire Shunt Active Power Filter (3P4W2C SAPF). The 3P4W electrical distribution system have been widely used to deliver power to single-phase and/or three-phase loads. They cause harmonics, reactive power burden, unbalanced currents and excessive neutral current. This problems reduce power quality, system efficiency and increase losses in system. To overcome this issues four-wire shunt active power filter is used. In this paper 3P4W2C based on Instantaneous Reactive Power Theory (p-q Theory) and Synchronous Reference Frame Theory (SRF Theory) is simulated. All simulation done in PSIM Version 9.0 software.
