Using multiple energy sources in electric vehicles (EVs) and dc grid presents a practical solution to circumvent concerns about fuel usage and battery range. Battery packs, fuel cells, ultra-super capacitors, and solar PV offer more viable energy options for propelling onboard electric motors and other supplementary EV components. To manage power distribution among input sources, loads, utility grids, and EVs, a multiport converter becomes necessary. In most cases, these converters employ a time-sharing strategy where only one energy source connects to the load, leaving others dormant within specific duty cycle parameters. This approach also has limitations related to duty cycle range or inductor charging. In this proposed study, a new configuration employing a dual-input dual-output converter is devised to concurrently manage loads without operational restrictions. This design effectively tackles the challenge of cross-regulation and enables both buck and boost voltage conversion simultaneously by adeptly controlling switches through a suitable strategy. This article outlines the converter's operational modes, and a design prototype (300 W) along with its corresponding test results are presented to validate its viability.

This article proposes a novel Boost-SEPIC-based three-port converter (TPC). The converter is developed for a standalone dc microgrid with roof-top solar PV panels in an electric boat (E-boat). The proposed converter is compact and requires a minimum number of components compared to the existing TPCs. It eliminates the need for three different dc–dc converters to charge, discharge the battery, and supply power to the load. A simple control is designed to effectively manage the energy extracted from PV by storing it in a battery and delivering continuous power to the load. The proposed TPC has other advantages, such as complete control over load voltage and low current ripples during the transient period. It can swiftly change among different modes of operation by detecting the load variations, Battery SOC, and PV availability, thereby ensuring continuous power flow towards the load. A front-end boost converter is used for maximum power point tracking. A single control is designed for the entire system to operate in a closed loop. The topology is designed and analyzed using Matlab -SIMULINK environment and validated on a laboratory prototype developed. Continuous power flow to the load in different modes of operation has been presented.

This study aims to present a cascade-free finite-control-set model predictive control (MPC) strategy for machine-side converter as well as grid-side converter of a large-scale wind turbine system (WTS). The proposed cascade-free MPC is applied to a direct drive (DD) permanent magnet synchronous generator (PMSG) to increase its energy output. To do this, a hybrid maximum power point tracking (MPPT) method, which is the combination of both the optimum torque MPPT method as well as the tip speed ratio MPPT method, is implemented in the proposed MPC to capture maximum power from the available wind. This proposed MPC controls electromagnetic variables and electrical variables in the same control structure, thus increasing the dynamic responses of the system. Similarly, the active and reactive power control presented in this study is done using the MPC by decoupling the grid currents during the current control. Finally, the control strategy proposed in this study demonstrates its applicability through a numerical example of a DD PMSG-based WTS with power rating, and demonstrates its superiority compared to existing control methods.

Hybrid compensated inductive power transfer (IPT) systems offer high tolerance to pad misalignments, but achieving maximum efficiency with conventional control strategies still remains challenging, especially under significant variations in mutual inductance ( $M$ ) and output power ( ${{P}_{text{out}}}$ ). This article, therefore, proposes an optimal control strategy, based on all four variables, to maximize the efficiency of hybrid IPT systems regardless of $M$ and ${{P}_{text{out}}}$ variations. Maximum efficiency is realized by meeting optimal conditions, and it involves maximizing the ac–ac efficiency through impedance matching and minimizing converter switching losses through zero-voltage switching. As hybrid IPT systems are complex in nature, these optimal conditions cannot be determined using conventional analytical methods. Hence, this article presents a novel two-step strategy that first numerically derives the optimal conditions and then determines the optimal variables using a numerical algorithm. The proposed numerical strategy is highly versatile, as it avoids cumbersome analytical derivations, overcomes the challenges of high nonlinearity and, more importantly, is applicable to IPT systems with any compensation topologies. The proposed strategy is experimentally validated using a 3-kW hybrid compensated prototype IPT system, benchmarking against traditional control strategies, and results are presented to demonstrate how higher efficiency can be achieved compared to traditional strategies under variations in $M$ , ${{P}_{text{out}}}$ , and output–input dc voltage ratios.

An onboard charger segment is currently dominated by two-stage charger designs, which suffer from drawbacks such as large size, low efficiency due to a high component count, elevated cost, and intricate controller requirements. To address these challenges, this work explores the implementation of an isolated bridgeless version of a modified single-ended primary inductor converter (SEPIC). This innovative approach aims to develop a single-stage, high-power factor battery charger tailored for light electric vehicles (LEVs). In addition to achieving high power factor operation, maintaining continuous input and output currents, and enabling high voltage conversion ratios, this charger utilizing modified SEPIC converter is specifically engineered to alleviate voltage stress on power switches within the converter circuit. This charger operates in discontinuous conduction mode (DCM), offering several notable advantages. These include inherent power factor correction capability, reduced control effort, minimized size of magnetic components, and fewer sensors, ultimately leading to a significant reduction in overall implementation cost. This article aims to validate charger's operation, elaborate on design of its components, outline control algorithm design, and demonstrate performance of both components and control logic through test results from hardware prototype developed, for a power level of 500 W.

In a fuel cell vehicle (FCV), the dc–dc converter is an integral part. Active switched inductor/capacitor (ASISC)-based topology is an attractive solution for FCV because it has low switch voltage stress, current stress, and simple design and control. However, the voltage stress in the switches of an active switched inductor (ASI) network is very sensitive to the switch's capacitance and inductance values. The inductors and drain-source capacitors of the switch constitute a resonance circuit due to the parameters' inconsistency of the ASI network. This introduces voltage oscillation across switches and eventually, the switch voltage stress shoots up. The oscillating voltage increases the power loss in the converter. In this article, a new hybrid structure of an ASISC dc–dc converter is derived. The proposed converter provides a high voltage conversion ratio, mitigates voltage oscillation across switches, resulting in reduced voltage stress across switch, and provides common ground between source and load ends. This article gives the converter key waveform, operating principle, detailed steady-state analysis, and design equations. The voltage conversion ratio, voltage stress, and current stress are derived and compared with existing ASISC converters. Finally, the prototype is developed and the working is demonstrated with 300 W for voltage conversion from 35 to 300 V.

In this article, a new four-level shared switch converter with a buck–boost-based energy recovery stage is proposed for a switched reluctance motor drive. The proposed converter achieves a higher demagnetization voltage with a much lower voltage rating of the energy recovery capacitor, as compared to other energy recovery-based converter variants. Furthermore, the voltage ratings of the active switches in the proposed converter are lesser than that of the conventional converters, for a given demagnetization voltage. The availability of soft-chopping operation in the proposed converter is beneficial for reducing the high-frequency ripple in the torque and lateral vibration of stator poles. This article presents the converter topology, its operating modes, and the design of the energy recovery stage in detail. Experimental results are presented to show the drive operation of an 8/6 switched reluctance motor driven by the proposed converter. A detailed comparison of the proposed converter with the conventional counterparts is also presented.
