This paper deals with the implementation of a reduced multilevel connections (RMC) as Voltage Source Converter (VSC) in Shunt Active Power Filter (SAPF) for harmonic mitigation in Power system. The design mainly focuses on the voltage source converter of SAPF. The developed modular structure produces 9,11,13,15,17,19,21,23,25,27,29,31 output levels using symmetric and asymmetric PV sources. This paper mainly focuses on a robust design of power circuit (RMC) and control circuit (SHE controller) for obtaining required voltage levels. Hence, to design a 27-level inverter, the traditional clamped topology requires 52 switches, the Cascaded H bridge (CHB) topology requires 52 switches and in the proposed RMC only 12 IGBTs are needed to produce 27 level. An added advantage of these topologies are they produce less total harmonic distortion by increasing the output levels. The design includes a comparison of 27-level reduced multilevel connections (RMC) topologies suitable for asymmetric input sources from solar photovoltaics (SPV). Further the loss calculation and the cost analysis are done to make the inverter superior than the conventional topologies. The implementation of RMC with the selective harmonic elimination method mitigates harmonics in the system. The proposed system is modeled using MATLAB/Simulink. An Experimental setup of the suggested SAPF is established and experimentally investigated. A 3 KWp solar PV plant is used to feed the DC input to the developed prototype. Based on the findings, it can be concluded that the suggested inverter reduces the harmonics, compensates reactive power, improves power quality, lessens the components, lessens the size and reduces the cost.

“…Later, more researchers presented FLCs in the literature dedicated to controlling PQ using filters and specialized devices [8][9][10]. Table 1 shows a historical sequence of 17 FLCs proposed for PQ improvement in the literature [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. A review of the works published in the 1990s reveals that FLC research was initially focused on reactive power compensation, power factor rise, and voltage and frequency regulation, i.e., power system stability [31].…”

Fuzzy-based control systems have demonstrated a remarkable ability to control nonlinear processes, a characteristic commonly observed in power systems, particularly in the context of power quality enhancement. Despite this, an updated and comprehensive literature review on the applications of fuzzy logic in the domain of power quality control has been lacking. To address this gap, this study critically examines published research on the effective and efficient use of fuzzy logic in resolving quality issues within power systems. Data sources included the Web of Science and academic journal databases, followed by an evaluation of target articles based on predefined criteria. The information was then classified into seven categories, including control system type, features of the fuzzy logic controller, fuzzy logic inference strategy, power quality issue, control device, implementation methodology (efficacy testing), and efficiency improvement. Our study revealed that fuzzy-based control systems have evolved from simple type-1 fuzzy controllers to advanced control systems (type-2 fuzzy and hybrid) capable of effectively addressing complex power quality issues. We believe that the insights gained from this study will be useful to both experienced and inexperienced researchers and industry engineers seeking to leverage fuzzy logic to enhance power quality control.

“…Therefore, the random PWM strategies along with three main modulations are: Randomized Carrier-Based (RCB), Randomized Space Vector (RSV), and Dithered Sigma-Delta (DSD). In last 40 years, RPW strategy have been applied for DC-AC converters [9]- [12], random multi-carrier inverter [13]- [14], and filter active converter circuits [15]. In proposed system is reduced cost of the filter.…”

Pulse width modulation (PWM) is a powerful technique employed in analog circuit convert with a microprocessor based digital output. Besides, Pseudo Random Multi Carrier (PRMC) involves in two random PWM strategies to minimize the harmonic order for 9- level cascaded multilevel H-bridge (CHB) inverter and 9-level Modular Multilevel inverter are introduced. The design mainly focuses on the (Pulse Width Modulation) PWM method, in which two nearest voltage levels are approached in estimated output voltage prediction based on the Partial swarm optimization (PSO) algorithm, and it conveys a random variation in the pulse position of output by Pseudo Random Multi Carrier- Pulse Width Modulation (PRMC-PWM). The CHB and the Modular inverters generate low distortion output by using PMRC. The simulation and prototype circuit are developed for the nine level output using sixteen switches and ten with Resistive-Inductive (R-L) load variation condition. The power quality is improved in CHB and Modular inverter (MoI) with minimized harmonics in various modulation index (MI) as varied from 0.1 up to 0.8. The circuit is designed by using a Field Programmable Gate Array (FPGA), Implementing a PSO algorithm for both CHB, and MoI are proposed. The comparisons of results are verified with lower order harmonics and find the best switching angle across the MLI switches. Modular inverter furthermore investigates with PRMC, Random Nearest level (RNL) modulation scheme are presented, and the proposed circuit is along with the respective degree of the output voltage were synthesized in non-linear load by the development of reactive power across a motor load.
