The proposed 3L-NPC-DBSRC is able to realize increased voltage gain and reduced harmonic components in the primary-side high-frequency-link voltages and currents. By using fundamental harmonic analysis (FHA), the steady-state operation principles of 3L-NPC-DBSRC are thoroughly analyzed in both forward and backward power-flow directions. Furthermore, a control algorithm based on globally optimal condition (GOC) is proposed for achieving zero-voltage switching (ZVS) in all switches and minimum root-mean-square (RMS) ac-link current, thus simultaneously reducing the switching and conduction power losses, and eventually resulting in high overall efficiency. Finally, to verify the effectiveness of the proposed 3L-NPC-DBSRC and its control method, both simulations and experiments are carried out on a designed example.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"1641-1655"},"PeriodicalIF":3.9,"publicationDate":"2025-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11186209","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255846","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}

To address these issues, there is an urgent need for RESs to actively support grid operations. This essential capability is facilitated by high-performance power conversion systems and advanced control strategies. Among various RESs, wind turbines (WTs) and photovoltaic (PV) systems, equipped with partially or fully rated power electronics converters (PECs), are the most promising solutions. Since these systems often operate below their rated capacity, the available power headroom can be effectively utilised to provide ancillary services. By employing advanced grid-supporting controls and coordination techniques, WT and PV systems can further enhance grid stability by providing voltage regulation, frequency stabilisation, and low-voltage ride-through (LVRT) performance. This paper addresses this timely and critical topic by exploring the contemporary control and coordination strategies that enable WT and PV systems to deliver essential grid-supporting services. The scope of discussion encompasses not only the control strategies for individual RESs but also the system-level coordination using decentralised, distributed, and centralised methods.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"1609-1640"},"PeriodicalIF":3.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11182318","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145255914","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, the high dV/dt and parasitics in the transformer and switching devices can cause ringing (oscillation) in the collectors of the switching devices and transformers. This paper analyses the main causes of conducted common-mode emissions of solid-state transformers, including experimental measurement techniques for leakage inductance and parasitic capacitances of a transformer. In addition, the impacts of snubber and decoupling capacitors on the conducted emission and switching losses, considering single-phase shift and triple-phase shift modulations, are presented in time and frequency domains. On top of that, the effect of DC-link capacitor type on conducted emissions is investigated. Based on the experimental results, the parasitic capacitances of the switching devices and the transformer are the main propagation paths of the conducted common-mode emission. Decoupling capacitors reduce the high-frequency oscillations, but the value should be selected carefully to avoid resonance in the low-frequency ranges. Triple phase-shift modulation reduces the AC link reactive current, but it increases both conducted CM emissions and switching losses, while single phase-shift modulation increases the reactive power and reduces the conducted CM emissions.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"1571-1582"},"PeriodicalIF":3.9,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11168254","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141597","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, operational constraints related to fuel supply conditions aimed at maintaining high stack efficiency can cause fuel starvation under rapid power variation. This issue introduces ramp rate limitations analogous to those observed in synchronous generators (SGs). To overcome this constraint, this paper proposes an advanced GFM control strategy for PEMFC power conversion systems, explicitly considering power ramp rate limitations to prevent fuel starvation. In the proposed algorithm, a two-stage converter fully replicates the actual behavior of the SG in a stage-wise manner, while an enhanced current-limiting scheme precisely saturates overcurrent and improves dynamic performance during fault transient. The DC/DC converter functions as a prime mover to regulate damping power from the stack, thus it effectively eliminates limited GFM problems. In addition, the DC/AC inverter emulates the electromechanical response of the SG to compensate for power imbalance caused by the stack’s power ramp rate; the DC-link capacitor effectively serves as an energy buffer to prevent fuel starvation. The practical feasibility of the proposed GFM algorithm for the PEMFC system is experimentally evaluated using hardware-in-the-loop testing.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"6 ","pages":"1559-1570"},"PeriodicalIF":3.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11162718","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141598","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}

Numerical methods, e.g. FEM, are accurate but are very time consuming for calculating the losses of litz wire windings and therefore cannot be integrated in converter optimisation routines, which require a fast execution due to the large number of evaluations.

The application range of the proposed model covers inductors using cores with single and discrete gaps, and iron powder cores with distributed gaps.

Then, the transfer-function-based ABMs of CIRs are aggregated along with their collector lines and impedance/ admittance-based model (I/ABM) of any other connected components, such as loads. The use of I/ABMs enables scalable aggregation of all CIRs, including those with fully known dynamic models, as well as those whose models may not be disclosed by manufacturers. This step is followed by the model-order reduction in the frequency domain. These steps result in the reduction of the computational complexity of the individual subsystems.
