Abstract: In order to support the superiority of one current control strategy over the other, this paper provides a detailed performance analysis of SAPF under two current control strategies: synchronous frame reference theory (d-q) and instantaneous active and reactive power theory (p-q). In both approaches, a reference current is produced for the filter that corrects the power system's reactive power or harmonic current component. This study describes a current controller called a harmonic current controller, which helps to eliminate harmonics by providing the IGBT inverter with a corrected gating sequence. In this study, traditional PI controllers and fuzzy logic controllers are employed to generate pulses properly.
