Conventional control solutions rely on bilateral band-pass filters with finite gain at harmonic frequencies, offering only limited suppression of unbalanced and harmonic voltages. This article proposes a novel complex-valued control strategy employing unilateral band-pass filters with infinite gain at selected harmonic frequencies. Implemented as an outer control loop in parallel with the standard droop control and virtual impedance, the proposed control is sequence-selective, targeting only the dominant harmonic and negative-sequence components actually present. This yields two key advantages: first, unbalanced and harmonic voltages are suppressed to practically negligible levels; and second, the compensation task is decoupled from the inner loops, allowing their phase margins to be preserved while the stability of the outer loop is guaranteed independently. The effectiveness of the proposed approach has been validated through experimental testing on a laboratory-scale islanded AC microgrid, including dynamic transitions between balanced, unbalanced, and nonlinear loading conditions with plug-and-play operation.

Among these strategies, gate voltage modulation offers a way to influence the power losses without compromising signal quality. However, existing implementations often require multiple isolated supplies or modifications in high-voltage side circuitry, increasing complexity and cost. This work presents a Variable Voltage Supply (VVS) that enables gate voltage modulation without requiring signal isolation or changes to the gate driver high-voltage side. The circuit is based on a fixed-output flyback supply design, modified to allow multi-level programmability using primary-side regulation and a digitally controlled resistor network. This configuration enables microcontroller-based selection of four output levels (15 V, 17 V, 18 V, 20 V), with a voltage slew rate of 60 mV/<inline-formula><tex-math>$mathrm{mu }$</tex-math></inline-formula>s. The added functionality results in a component cost of 12.41 €, representing an increase of 0.15 € compared to the original design. The circuit is compatible with both MOSFET and IGBT technologies, and can be directly integrated into existing converter platforms. The concept has been validated experimentally, and results confirm that increasing the gate voltage reduces steady-state junction temperature. In addition, the article also discusses the main limitations of the approach (e.g., increased short-circuit stress at high gate voltages) and outlines potential improvements including dual-polarity supply extension and closed-loop ATC strategies, among others.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"776-792"},"PeriodicalIF":3.9,"publicationDate":"2026-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11404199","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362352","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}

This is enabled by using specially designed software and hardware that serve as an interface between the modeled environment and the equipment under test. Using PHIL for testing and validation can help significantly reduce time-to-market for novel energy solutions by both reducing the number of design/prototyping iterations, which in turn reduces the development costs, and the need for timely and costly field tests later during the system validation stage. The PHIL as a technology has been studied over the last 20 years, focusing mostly on the software/hardware interfaces and on system stability challenges. However, there has not been a consensus yet on how a PHIL system should be designed, validated and operated to maximize its benefits. The present work provides answers to these questions.

The performance of NPC-3LI can be further improved by employing a low-loss 240<inline-formula><tex-math>$^{circ}$</tex-math></inline-formula>-Clamped Pulse Width Modulation (240CPWM) technique. 240CPWM is currently the lowest switching loss PWM method in cascaded configurations comprising a dc-dc stage followed by a dc-ac stage, reducing the dc-ac stage switching losses by at least 80% compared to the conventional Space Vector PWM (SVPWM) at unity power factor. In this work, the performance enhancement of NPC-3LI using 240CPWM in terms of total harmonic distortion (THD) and switching loss is presented and compared with benchmark PWM methods. The THD analysis is carried out using the concept of virtual stator flux ripple, and power losses (switching and conduction) are derived by analyzing the switching device characteristics and the phase relationship between the modulation voltage and output current. A three-closed-loop control method is also developed for the front-end boost converter to achieve an effective neutral-point voltage balance. The analytical results are validated using a 3 kW experimental prototype.

In this context, this paper proposes a Model Predictive Control (MPC) based power management designed to mitigate Li-ion battery degradation while improving the overall system efficiency. To validate this proposal, extensive experimental results are presented. The proposed formulation aims to minimize battery stress by smoothing the current profile and reducing cycling effects. The performance of the MPC power management is verified through a comparative experimental analysis of four distinct strategies: rule-based, frequency-filtering, a benchmark MPC, and the proposed MPC. Evaluation is based on four key metrics: RMS current, total power losses, Equivalent Full Cycles (EFC), and State of Health variation (<inline-formula><tex-math>$Delta$</tex-math></inline-formula>SOH). Experimental results demonstrate that the proposed method outperforms the compared strategies across all evaluated criteria, significantly reducing battery stress in terms of cycling and current distribution. Furthermore, long-term simulations corroborate these findings, showing a substantial reduction in battery degradation compared to other established methods. These results confirm that the proposed method, provides a robust solution for mitigating battery degradation in hybrid inverter applications.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"759-775"},"PeriodicalIF":3.9,"publicationDate":"2026-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11397492","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147362354","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}

Further analyses are provided on the maximum power transfer mechanism, the ZVS criterion and its variation with the module number, and parameter sensitivity, thereby establishing a theoretical basis for analysis and fine parameter design of modular paralleled single-switch systems.

The DGe integrates a permanent-magnet (PM) rotor that produces a fixed air-gap flux and a wound-field (WF) rotor that provides controllable excitation through a DC field current. Since passive rectification prevents reverse power flow and requires the generator voltage to remain compatible with the DC-link voltage, a wound-field excitation controller is developed to regulate the generator back-EMF in real time and maintain DC-link voltage stability under varying load conditions. A dynamic model of the DGe is established and used to derive the control law linking the WF excitation to the required rectified voltage. The nine-phase configuration reduces per-phase current stress and significantly lowers DC ripple compared to the three-phase case, enabling smaller DC-link capacitors and improving system robustness. The proposed architecture and control strategy are validated through simulations and experimental studies on a reduced-scale prototype, demonstrating effective DC-link voltage regulation and stable operation.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"557-569"},"PeriodicalIF":3.9,"publicationDate":"2026-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11395405","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146223575","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}
