“…hybrid technique for regulating a single-phase active power filter using interleaved bridge converters is discussed in [5,11,12]. An interleaved buck converter is utilized within a shunt active power filter utilizing a hybrid controller for fuzzy based control and it discusses a PV system interleaved with a buck converter [7,8,13,14,15] outlines a buck converter interleaved with a shunt active power filter for optimal control. This article [9,10] models and controls an interleaved buck converter active power filter.…”

This paper discusses the modelling and control aspects of an enclosed lowest converter-based shunt active power filter. In an AC distribution network, the shunt active power filter reduces harmonic interference. Using an interleaved buck converter architecture prevents the typical inverter’s shoot-through problem. The P-Q control method is utilised to provide compensating current. One loop controls the dc-link voltage while the other regulates the voltage mode. This technique uses a twin-loop architecture. For example, the park transformation and inverse park transformation are used in the current loop to take the load current into account. Current is controlled using hysteresis using a current limiting device. PWM is used to create switching pulses by the gate driver, a digital signal processor. All three parameters of a non-ideal voltage source can be figured out. For an unbalanced nonlinear load, the voltage at the source, the load’s current, and the source’s current have all been provided.

“…Buck converters, also known as step-down converters, are widely used in applications where a regulated voltage needs to be obtained from a higher voltage source. Examples of such applications are industrial applications [1,2], like motor drives or factory automation [3,4], telecommunications [5], solar power systems [6], automotive [7], and voltage regulators [8][9][10][11][12]. This ability to reduce the voltage level is essential in many electronic devices, and in the literature, different topologies, starting with the classical step-down buck converter [13], other types of non-isolated [14,15] converters or isolated step-down converters [16][17][18] can be found.…”

This paper aims to outline the process of dimensioning a controller tailored for a fourth-order step-down converter. In order to conduct a thorough small-signal analysis, it is imperative to find the state–space model in matrices form. Given its fourth-order nature, the control-to-output transfer function also aligns with this order, although its degree is ultimately reduced to a second-order using the tfest function. It is remarkable that the design of the type III error amplifier assumes a central position in the overall controller design process. The theoretical analysis was then subjected to rigorous validation via simulation, with particular attention paid to the step response in both input voltage and output resistance. This study developed from the desire to validate the efficacy of reducing the control-to-output transfer function degree using the tfest function, aiming to highlight a fourth-order converter to which controller design theory can be applied, related to that for a second-order converter.

“…However, the aggressive nature of the controllers is not satisfactory during load and grid dynamic conditions. [12][13][14][15][16][17] To overcome the above limitations, few adaptive control schemes have been reported in the cited works. These types of control schemes have been introduced to increase the system behavior during dynamic conditions and also utilized to improve the power quality, grid synchronization, fundamental component extraction, dc-off set elimination, and low computation burden.…”

“…In the literature, several control schemes have been introduced for the grid-forming inverter by using the shunt APF on the simulation as well as experimental in grid integration with RPGS applications. Conventionally, instantaneous reactive power (IRP), 12 improved IRP (IIRP), 13 synchronous reference frame (SRF), 14 improved SRF (ISRF), 15 instantaneous symmetrical component (ISC) 16 and Fryze 17 theories have been reported. The conventional control schemes have been employed to control the grid-forming inverter control with power quality enrichment.…”

In this paper, an improved fractional order notch filter (IFONF)-based gridforming inverter control scheme is employed to mitigate the harmonics in photovoltaic system applications. Moreover, a fuzzy gain tuning proportionalintegral-derivative (FTPID) controller is developed for the dc-link voltage to maintain its reference value. The proposed FTPID-IFONF control scheme is executed to evaluate the active fundamental weight components (FWC) of the load currents and distorted grid voltages consequently generates the PWM pulses to the grid-forming inverter for power quality enrichment in a grid integration with photovoltaic applications. The integer order based filters have some constraints due to differentiator term and fixed integrator. For this reason, an improved design of an integer order notch filter is suggested in the proposed FTPID-IFONF controller scheme. The behavior of the proposed FTPID-IFONF control scheme is found good in-terms of elimination of dc offset, grid-synchronization, separation of fundamental components, adaptive behavior and harmonic elimination at the consumer terminals. The proposed controller is validated under several load and grid dynamic conditions such as steady-state, grid voltage sag-swell, distorted, load dynamic and removed conditions on MATLAB/Simulink platform. A prototype PV integrated with grid setup is constructed to validate the proposed system in the real-time. The FTPID-IFONF control scheme is well justified under several grid and load dynamic conditions and the harmonic distortions of the grid characteristics are found well based on the limits of IEEE-519 standards. A comparative study is also analyzed to show the effectiveness of the controller with recently published works.
