“…To evaluate the proposed method efficiency, Table 4 shows a performance comparison between the proposed strategy and other strategies recently adopted for APF control [16,17,20,[36][37][38][39]. This comparison was based on inverter flying capacitor voltage ripple rate ΔVc% under ideal and non-ideal grid voltages after SAPF connection, transient regime capacitor voltages overshoot and undershoot and maximal ΔVc%, transient response time Δtset for capacitor voltage rebalancing to reach their references, grid problem number for which robustness has been tested and based on cost and complexity in terms of devices used such as regulators, sensors, and measuring instruments.…”

“…Considering MLI-based A.P.F, where the number of parameters to be controlled is very important, adaptive PI control seems to be unable to control. The development of cascaded MLI-based APF with reduced transformers is proposed in [20], this method is not enough accurate. Furthermore, the inverter output voltage is poor, the transient regime time and overshoot at disturbance instant are important.…”

In this work, the authors are considering the problem of compensation of harmonic current absorbed by a non-linear load from a three-phase grid voltage. The objective is twofold: the first is to reduce cost and control complexity by avoiding proportional-integral regulators and optimising measurement instrumentation while ensuring inverter capacitor voltage selfbalance and the second is to provide a robust control strategy against power grid problems. Without measuring current and capacitor voltages, the proposed control strategy generates accurate control signals able to ensure flying capacitor inverter selfbalance and full compensation of harmonics whatever the grid voltage problem. In this regard, the robustness of the proposed control against power grid problem such as sag, swell, grid voltage unbalance, and frequency variation have been tested while proving its efficiency to compensate for harmonic currents and ensuring capacitor voltage natural balance even in transient regimes. During balanced and unbalanced loads, the proposed method has exhibited an excellent transient response, represented by capacitor voltages tracking to their reference in the presence of large variation in the load. Finally, effectiveness of the proposed control strategy is verified by numerical simulations as well as realistic experiments, and its merits are showed in comparison with other methods. * = V * c i, j I * c i, j reference capacitor power I d non-linear load current R, L load resistive-inductive load

“…Since SAPF is used for compensating load harmonic currents, it is common to simplify the load into a harmonic current source in the modeling of SAPF [13][14][15][16]. Research effort has been mainly put on current control strategies [17][18][19][20][21][22], topologies [23][24][25], and reference current extraction methods [26][27][28] to enhance the harmonic compensation performance. It takes for granted to consider SAPF to be in favor of system stability by eliminating harmonic currents.…”

Owing to the use of nonlinear loads in the distribution side, there are power quality issues such as voltage swell/sag, harmonics, flickers, voltage imbalance, and outage. The harmonics in power system affect the quality of power and hence a suitable methodology is vital to mitigate the harmonics and compensation of reactive power. In this paper, CNN (Convolutional Neural Network)-based harmonic mitigation is performed. A 5-level cascaded H-bridge inverter is employed as a shunt active filter in which the reference current is generated by the SRF theory, incorporating CNN for harmonic extraction. The DC-link potential across capacitor is retained by means of ANN (Artificial Neural Network) controller whose behaviour is compared with a proportional controller as well as FLC. The gating pulse for the cascaded inverter is generated by means of PWM generator incorporated with Hysteresis Current Controller (HCC). By this control strategy, the harmonics in the current and voltage get mitigated; subsequently, the reactive power compensation is achieved with unity power factor. By implementing the five-level inverter, the THD and the settling time are minimized. The performance of the system is analysed using MATLAB for nonlinear load and the hardware is implemented with FPGA Spartan 6E. The THD of 0.93% is accomplished in simulation and 1.4% in the hardware execution.
