“…Therefore, three fictitious two-phase systems, represented by (6), are obtained in the αβ -axes, and the transformation from the stationary three-phase frame abc into stationary system 0 αβ is not necessary. Thus, only the transformation from αβ -axes into dq-axes is taken into account, as given by (2).…”

This work presents a study of shunt active power filters (APFs), which are implemented by means of both fourlegs and three full-bridge voltage source inverter (VSI) topologies. These topologies are applied in three-phase four-wire systems for reactive power compensation and harmonic current suppression generated by nonlinear loads. The compensation reference currents used in both APFs are extracted from the synchronous reference frame (SRF) based controllers. A mathematical analysis of the four-legs and the three full-bridge topologies are presented in order to obtain the model in state space and the transfer functions of each system, allowing to set the proportional-integral (PI) gains used in the current controllers. Simulation results are presented in order to evaluate the performance of the APFs approaches.

“…In this case, the compensation of the unbalanced load is not taken into account [7]. This paper presents a study of two APF topologies, which are applied to three-phase four-wire systems, such as the four-legs (F-L) [3][4][5][6], and three full-bridge (3F-B) [3,[7][8][9], as shown in Fig. 1 and Fig.…”

“…In provision of unbalanced loads connected to a four-wire three-phase system, the fundamental currents are represented by positive-negativeand zero-sequence components, such as ( unique three-phase load which are represented into the synchronous reference frame ( -axis), the SRF algorithm allows this extraction perfectly with some modification that must be done to apply it to a three-phase system, as can be seen in Figure 2. So we can obtain three independent transfer functions as given by (7) and 8,…”

“…Lastly, a precise conclusion has been added in section 5 to finalize the work. Figure 1 shows the scheme that represents the a SAPF topology applied to a three-phase system using a four-leg full-bridge VSI converter [7]; the four-leg SAPF is connected in parallel with the AC three-phase four-wire system through four inductors. The inductances L f are used to reduce and smooth the ripples of the harmonic currents injected by SAPF and the capacitor is used to stock energy.…”

This work presents a simulation of Three-Phase Four-Wire Shunt Active Power Filter (SAPF) destined to suppress harmonic currents generated by nonlinear loads. The SAPF guarantee also the compensation for unbalanced nonlinear load currents, reactive power and harmonic neutral current. The identification method is based on the synchronous reference frame. In order to have good performances of DC voltage control, simplified Backstepping control for three-Phase four-Wire (SAPF) system is proposed. Complete simulation of the resultant active filtering system validates the efficiency of the proposed simplified Backstepping control law over to the traditional control with PI controller.

“…According to its procedure connection in the power system, there are two types of APFs: Series APF and parallel APF. Research and applications show that the series APF is selected to compensate the harmonic voltage-source, while shunt APF is more appropriate to compensate the harmonic current source [15]. APF which is at most used as a current or voltage harmonic compensation, can be divided into AC and DC filters.…”

This paper intends to present the recent development of artificial intelligence (AI) applications in active power filter (APF). As a result of the development in power electronic technology, (APF) continues to attract ample attention. Compared with the traditional reactive LC filter, active power filter is considered to be more effective in compensating harmonic current generated by nonlinear loads. APF, can correct the power quality and improve the reliability and stability on power utility. A brief explanation of some important areas in AI and a comprehensive survey of the literature along the main categories of AI is presented to introduce the readers into the wideranging topics that AI encompasses. Plenty of relevant literatures have been selected in the review, mostly emphasized on better accuracy, robustness, efficiency, stability and tracking ability of the system.
