Type: article
Abstract: This paper presents a new control strategy to improve the performance of shunt active power filter (SAPF) in three-phase four-wire system when operating under an unbalanced system. A control method based on the instantaneous power theory have been used and discussed. On the other side, a three-dimensional hysteresis current controller is used to track the compensated current references. This scheme requires the service of a phased-locked loop (PLL) to make the system insensitive to the distortions that are generally present in the utility voltages. The performance of the proposed topology under the used control approach has been finally discussed through the obtained simulation results.
