This paper presents the modeling and control of Air Breathing Fuel Cell (ABFC) and solar PV based power system for feeding the voltage regulator module of a laptop computer. The MATLAB modeling comprises of power sources as well as power conditioning units (PCUs). The different power sources under consideration are ABFC stack and solar PV module feeding the PCUs. The quadratic buck converter (QBC) and boost converter combination are used as a power conditioning unit (PCU). The average current mode control (ACMC) based QBC enables good steady state and dynamic voltage regulations. The perturb and observe (P&O) algorithm is used for maximum power tracking of solar PV panel. The efficiency analysis of ABFC power system and PV module power system are represented.

<span lang="EN-US">The power factor is a significant concern in power systems. The significant power loss occurred due to electronic and electrical equipment damages affected by the deviation of physical characteristics, including voltage, current, and frequency parameters.The power loss and quality issues were resolved by introducing filtering techniques in electronic and electrical equipment. Many filtering techniques include passive filtering (PF), Active power filter (APF), and many hybrid approaches are already available. Most of these methods use proper compensation controlling approaches and failed to minimize the total harmonic distortion (THD), and harmonic mitigation in power systems has its best. In this article, an efficient Hybrid-APF using Artificial-Neuro Fuzzy interface system (ANFIS) for software and hardware perspective is designed. The proposed approach uses hybrid controlling strategies which include PI with artificial intelligence (ANFIS) controller, to control the power losses for H-APF. Additionally, current compensation is achieved by PQ-theory, followed by Hysteresis-Current- Controller (HCC). The hardware architecture of ANFIS with HCC is designed to improve the chip-area for real-time power applications.The present work analyzed by simulating the voltage and current waveform. The proposed-H-APF using ANFIS controller, both software and hardware approaches, is compared with other control techniques like H-APF with PI and Fuzzy logic controller by concerning THD,Reactive power, and Different Harmonics and loads improvements.</span>

In recent times resonant converters have become more popular due to the demand for xEV chargers increasing rapidly. Due to its unique characteristics in operating the converter in either zero‐voltage or zero‐current switching during switching conditions, hence it reduces the switching and conduction losses. From the literature, there are several converters in the resonating networks one of its own is inductor‐inductor‐capacitor (LLC), it has a drawback of higher conduction losses at light loads, poor transient performance, and stability. Hence, this article investigates an electric vehicle (EV) charger for xEV charging stations using an interleaved inductor‐inductor‐capacitor (iLLC) DC‐DC converter. It has features of lower losses during various loads, better transient performance with low ripples and stable regulation during sudden variations. An integrated closed‐loop technique is proposed with a constant voltage charging mode of operation, along with a hybrid control scheme of variable frequency + phase shift modulation (VFPSM). To examine the performance of the proposed system, it is compared with the LLC converter under similar operating conditions and a detailed steady‐state and transient analysis is presented. The prototype is built using GaN switches at a rated power of 3.3 kW at an efficiency of 98.2%.
