This article, therefore, proposes an optimal control strategy, based on all four variables, to maximize the efficiency of hybrid IPT systems regardless of \u0000<inline-formula><tex-math>$M$</tex-math></inline-formula>\u0000 and \u0000<inline-formula><tex-math>${{P}_{text{out}}}$</tex-math></inline-formula>\u0000 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 \u0000<inline-formula><tex-math>$M$</tex-math></inline-formula>\u0000, \u0000<inline-formula><tex-math>${{P}_{text{out}}}$</tex-math></inline-formula>\u0000, and output–input dc voltage ratios.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"19-29"},"PeriodicalIF":0.0,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The desirable features of such a system are lower device counts, continuous current ports for solar and battery, better power conversion efficiency, voltage boosting, maximum power point tracking, charge control of the battery, voltage regulation, and isolation. The existing schemes possess only some of these features. This article addresses this concern by proposing a two-stage stand-alone system with solar photovoltaic (PV) and battery. The main contribution of this article is a two-stage system consisting of a novel high-frequency transformer integrated three-port dc–dc converter (TPC) as the first stage, followed by an inverter to supply the ac loads. The operation of the proposed TPC is analyzed under different switching states with circuit diagrams and waveforms, and a control scheme is devised for the system to operate under different modes for seamless mode shifts. Further, selection guidelines for various components of the complete system are provided. The proposed stand-alone solution is validated through detailed analysis and experimental study on a 400 W prototype. The results demonstrate that the proposed system is superior to the currently available schemes.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"743-753"},"PeriodicalIF":0.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830453","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving high efficiency within a wide operating range while maintaining the unity power factor (PF) remains unsolved due to the single-stage structure. The difficulty is twofold. First, the full-range zero-voltage switching (ZVS) achievement at a wide operating range is challenging, which causes high switching loss. Second, sinusoidal input voltage leads to a high inductor current, which increases conduction loss. To address the aforementioned issues, this article presents an adaptive sinusoidal extended phase shift (ASEPS) modulation technique with a high PF for SSOBCs to minimize power loss and increase efficiency. First, aiming to minimize the switching loss, the proposed extended phase shift introduces one more degree of freedom in the secondary bridge to extend the ZVS technique range and flexibility, especially at a wide operating range. Then, combined with the ZVS condition, the minimal peak current optimization is presented to minimize the inductor current, which reduces conduction loss. Experimental results in a 6-kW silicon carbide-based SSOBC prototype verify that the proposed ASEPS technique increases efficiency by 1.7% compared to the existing pulsewidth modulation and by 0.6% compared to the nonextended modulation strategy.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"574-584"},"PeriodicalIF":0.0,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839863","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cogging torque causes acoustic noise and vibration. Therefore, it is important to know the value of cogging torque in the asymmetrical IPM machine. The cogging torque of the asymmetrical permanent magnet machine is computed based on a Fourier series expansion of air gap flux density in an equivalent slot-less IPM machine and relative air gap permeance function. The flux distribution of the asymmetrical IPM machine is computed using an equivalent lumped magnetic circuit based on flux distribution obtained using the finite-element analysis (FEA) method. The computed flux distribution follows the FEA results and thus the lumped magnetic circuit is validated. Then, the cogging torque of the asymmetrical IPM machine is derived. The Fourier coefficients of the flux distribution and relative air gap permeance in the asymmetrical IPM machine are analyzed and used to compute the cogging torque and compared to the FEA results. The computed cogging torque follows the FEA results and thus the newly derived cogging torque is justified by FEA and measurement. The FFT of the cogging torque is analyzed. Skewing technique is used to minimize cogging torque.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 3","pages":"877-887"},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144657504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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 converter has a modular construction based on building blocks named submodules (SMs). However, the large number of SMs required in a typical application makes operating the MMC through a centralized control architecture difficult. Recently, distributed control schemes have been proposed to provide a modular hardware and software development solution for the MMC. This control architecture allows a two-level hierarchy, in which there are distributed low-level control tasks among local controllers (LCs) placed in the converter SMs, while central controller (CC) undertakes high-level control tasks. Under this scheme, both LCs and the CC could execute their control algorithms at different time steps, optimizing the control hardware utilization: this has not been previously reported for MMC operating with a distributed control approach. Based on that, this article proposes an event-triggered distributed control scheme for regulating the capacitor voltages in the MMC. Contrary to previously reported works, the proposal only updates the control actions of LCs when a trigger event occurs, notably reducing the LCs hardware utilization. Real-time hardware-in-the-loop simulation studies validate the proposal's effectiveness, and its performance is compared with traditional consensus-based distributed approach, showing superior performance.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 2","pages":"536-546"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143839906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":100620,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Industrial Electronics","volume":"6 1","pages":"372-381"},"PeriodicalIF":0.0,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142905794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
