“…Although the classical AC/DC rectifier is considered as a polluting source of harmonics, it is, in addition to its economic aspect, very simple to install and maintain. Besides, active filters can be installed regardless of the load types and the perturbations to be eliminated, only its rated power must be a percentage of the perturbating loads [28]. SAF can compensate the perturbations caused by the nonlinear loads, particularly power electronics-based loads, while continuously tracking their changes [24].…”

“…Therefore, the SAF is recommended here to cancel out these perturbations and improve the power quality in the grid side of TR1. It is worth noting that the SL can be completely isolated from the perturbing voltage and current of the grid using a series active filter, which is more complicated to design, to install and to protect than a SAF, with an oversizing also [34,35].…”

This paper presents a free-harmonic AC/DC/AC converter structure using a novel modulation approach for Asymmetrical Cascade H-Bridge Multi-Level Inverter (ACHB-MLI) and, conventional rectifiers combined with a shunt active filter, for grid integration. The novel approach SMT-SHE combines two modulation techniques: the Staircase Modulation Technique (SMT) and the Selective Harmonics Elimination (SHE). SMT-SHE approach achieves a sinusoidal-like output stepping voltage with variable output voltage amplitude and free of wide band or/and specific harmonics to fulfill the sensitive loads specifications; by determining the appropriate SHE switching angles. The precalculated switching angles are optimized to minimize the number of H-bridge modules and lower the DC capacitors rating. Furthermore, a restriction on the switching angles is proposed to prevent the appearance of undesired harmonics (zeros, even) and consequently overcome the limitation of the SHE algorithm applicability. Finally, a real case study in textile factory is conducted, using real measurements provided by power quality analyzer measuring devices, to validate the proposed AC/DC/AC converter supplying a sensitive load of 50 kVA, given by an asynchronous motor drive.

“…Several works have been carried out for the development of the serial multicellular converters. Then, the authors of [20][21][22] have developed these structures and found adequate control strategies considering that this type of converters requires an in-depth study, especially with regard to the charges and discharges of floating capacitors [1,23,24]. The works of Guillaume Gateau led to two essential problems characterizing this type of converters, which are the saturation of the controls and the controllability of the floating voltages.…”

In this work, we represent a shunt active power filter (SAPF) based on a serial three-phase flying capacitor multilevel inverter (FCMI) controlled by a Petri Nets representation (PNs). This structure is chosen for its significant performances. In fact, the use of the FCMI within the SAPF makes it possible to increase the apparent switching frequency of the structure in order to reduce the value then the volume and weight of the inductance of the output filter. Besides, the FCMI allows the synthesis of a high-voltage signal using low-voltage semiconductor components. Therefore, improving the reliability of this structure leads to the improvement of the dynamics of the SAPF. This paper deals with a new control methodology based on PNs to regulate the flying capacitor voltages and the reference currents issued by the instantaneous active and reactive power theory. Compared to a conventional SAPF composed by a classical two-level inverter and controlled by a simple PWM control, simulation results demonstrate that our proposed control enhances the dynamic system and the power quality by reducing the total harmonic distortion (THD) satisfying the limits of IEEE standards.

The main purpose of this paper is the evaluation of the Shunt Active Power Filter apparent power ratio between the apparent power generated by the source power system to the load and the compensation apparent power produced by the shunt APF to force the currents circulating toward the source to be sinusoidal and balanced. This ratio allows defining the compensations capability for different perturbations in AC power system such as current unbalance, phase shift current and undesired harmonics generated by non linear load. This capability is determined by the maximum rate of the apparent power that can be delivered. In this paper a method of evaluation of this ratio is proposed, it is based on the definition of the effective apparent power as defined in IEEE 1459-2000 which was proved to be a suitable amount to be concerned in the design process of different devices.
