For conventional mechanical circuit breakers and future hybrid or solid-state devices, selectivity is, in line with AC practice, typically achieved by coordination based on their time-current trip characteristics. However, experimental short-circuit tests show that in DC-grids non-selective behavior can occur with high current slopes. To explain this effect, the delays until the fault current is effectively limited are analyzed. Based on this analysis, a critical time interval is identified and introduced as the reaction time gap. It describes the delay between the time when the circuit breaker should ideally trip immediately after detecting the fault and the time when it actually limits the current. To represent this behavior within conventional time–current characteristic curves, a measurement method for determining the relevant time intervals is proposed. A measurement-based study on several commercially available mechanical circuit breakers reveals the characteristics of short-circuit detection and current limitation, thereby confirming the existence of the reaction time gap and the resulting constraint on achievable selectivity. Possible countermeasures to overcome this reaction time gap relating to the behavior of the grid and the circuit breaker are outlined. Finally, the results and their implications for the design and protection coordination of DC-grids are discussed.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"1059-1074"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11447418","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148485408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, inductively coupled methods are particularly attractive for their practicality and safety, yet existing approaches are generally limited to single-impedance measurements or low-dimensional formulations, preventing the complete characterization of multiconductor systems. To overcome these limitations, this paper presents a generalized formulation for the impedance characterization of systems with an arbitrary number of ports, and derives an explicit solution for the three-port case. The proposed method is experimentally validated on passive three-port networks in the frequency range 150 kHz–110 MHz. Additionally, a mathematical framework for the evaluation of three-phase EMI filter insertion loss under realistic impedance conditions is introduced and, as an application example, the impedance matrix of a three-phase motor-drive system is identified and used for the assessment of an EMI filter performance under practical operating conditions.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"1967-1978"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11579515","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148485800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The testing is performed across all 36 modules of the pack. The platform integrates voltage sensors, balancing circuitry, and a micro-controller to enable safe, simultaneous cell screening without disassembling the modules. Using the proposed testing platform, cell voltage imbalances within each module are constrained to a defined reference value, and cell signals can be safely accessed, enabling accurate and non-invasive cell-level state-of-health assessments.

Five key aspects are investigated as follows: (1) evaluation of different detection signals and their combinations, (2) segment-wise analysis to identify waveform regions that contribute most to classification, (3) impact of waveform sampling rate on detection accuracy, (4) validation using mixed datasets from multiple modules, and (5) comparison between Si-IGBT and SiC-MOSFET devices. The turn-off gate voltage waveforms provide the highest accuracy, and a high accuracy of about 99 % was achieved even with downsampling from 2.5 GS/s to 100 MS/s. The mixed datasets show no degradation in accuracy, and the optimum gate drive condition for high accuracy differs between Si-IGBTs and SiC-MOSFETs.

Over the past decade, extensive research has focused on developing efficient converter topologies capable of accommodating a wide voltage gain range, including wide input or output voltage ranges. This paper systematically categorizes these converters into two main groups based on their approach to extending the voltage gain range (≥1:3). The first group includes topology morphing control (TMC) based DC-DC converters, which dynamically modify the converter topology through reconfiguration at either the input or output side, or by adjusting transformer turns ratio or resonant tank components. The second category comprises isolated buck-boost converters (IBBC), boost half-bridge converters (BHBC), resonant converters, and multi-phase converters. These converters achieve wide voltage gain ranges through structural modifications or control strategies. Additionally, each group is divided into subgroups that highlight their operating principles, features, and limitations. The paper also discusses challenges, including efficiency optimization and control complexity, in achieving wide voltage gain ranges.

Conventional auxiliary converters typically consist of a large number of power devices and require large inductors to suppress current ripple, which results in increased mass and volume. To address this problem, the proposed circuit uses a single auxiliary chopper circuit and transfers power using a triangular ac inductor current at high switching frequency, which reduces the size of the inductor. This paper focuses on the operating principles of the proposed circuit, and introduces an output power control circuit based on feedback control. The control circuit regulates the output power using the characteristics of the triangular ac inductor current to estimate the average output current, which enables output power regulation without a current sensor on the output voltage side, reducing costs. A simplified theoretical expression for the output power is derived with a direct relationship between the output power and triangular ac inductor current generation. The proposed control circuit is verified through experimental, simulated, and theoretical results, where output power is properly regulated under different operating conditions.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"1895-1910"},"PeriodicalIF":4.8,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11557604","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148442971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, charge trapping in the semiconductor material degrades several device parameters. While the dynamic on-state resistance and threshold voltage shifts are well-known, less studies have been conducted regarding parasitic device capacitances, although these have a significant influence on the switching behavior. Consequently, they also affect the switching losses and the safe operation of the semiconductor. Thus, characterization is necessary. As gate and drain bias are known to impact the trapping situation within the devices, the test setup to study the output capacitance should be capable of examining these parameters. Since charge trapping effects exhibit time constants in the range from µs to hours, the test bench should also cover this range. This paper therefore presents a test bench that addresses precisely these requirements. In a 650 V GaN-HEMT, the influence of the drain voltage on the output capacitance was found to be more pronounced than that of the gate voltage.
