However, frequency-impedance coupling (FIC) induced by PLL frequency deviation is often neglected in the conventional quasi-steady-state (QSS) PLL model, which may lead to an inaccurate post-fault stability assessment. To address this issue, this article proposes a 3-D frequency-impedance coupling (FIC) PLL model that explicitly incorporates frequency drift during faults, enabling whole-process transient stability analysis from fault occurrence to recovery. Based on that, the existence conditions of stable equilibrium points and the evolution of the domain of attraction (DOA) are investigated comprehensively with respect to grid strengths, PLL parameters, and fault durations. Furthermore, a DOA-oriented parameter design framework is developed to enhance transient stability. Finally, experimental results on a scaled-down GCC platform validate that the FIC-PLL model provides more accurate stability assessments than conventional QSS models, and the optimized PLL parameters effectively improve transient stability under weak-grid conditions.","PeriodicalId":13093,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Power Electronics","volume":"14 5","pages":"5760-5771"},"PeriodicalIF":5.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149097332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work advances existing active clamping module (ACM) to self-powered, bypass-capable modular switches (MSs) and proposes a dynamic clamping arm (DCA) control for series-connected MSs, enabling soft-switched recovery of turn-off energy and low-bandwidth sorting-based voltage balancing. The commutation process under DCA control is discussed in detail. Analytical models quantify voltage-balancing modes and derive design constraints for key parameters of a 10 kV/5 MW prototype. Performance comparisons of the proposed scheme with MMC and existing balancing methods are discussed. A phase-unit of the prototype, employing eight series-connected 1.7 kV IGBT-based MSs per arm, is tested in a power-cycling setup.

To address these gaps, a mathematical model of parallel VSG systems is developed. This model incorporates the dynamic characteristics of damping dissipation, system interactions, and reactive power control (RPC). Second, the feasible parameter region (FPR) is then determined to satisfy transient stability and rate of change of frequency (RoCoF) requirements under large disturbances.

During rapid cycling, residual energy and transformer leakage inductance (<inline-formula> <tex-math>$L_{k}$ </tex-math></inline-formula>) can induce large negative start-up current in the precharge phase, risking low-side switch (LSW) overstress and compromising high-side bootstrap reliability.

By eliminating the bleed path while preserving safe restart operation, the prototype achieves an 8.9% (29.3 mW) reduction in no-load input power at PD 48 V, contributing to improved standby efficiency and reduced energy consumption.

A phase-shifted full-bridge (PSFB) converter with series–series (S–S) compensation is considered, where the primary-side controller regulates the secondary charging current. Conventional proportional–integral (PI) control, tuned around nominal coupling, suffers performance degradation and even loss of convergence under coil misalignment and coupling variation. To address this, a twin delayed deep deterministic policy gradient (TD3) agent is used to adapt the PI gains online based on secondary-side feedback. The agent is trained in a Simulink environment and deployed in inference-only mode on a TI C2000 F28379D microcontroller, occupying approximately 25% of on-chip memory, demonstrating the feasibility of DRL-based adaptive control on resource-constrained embedded platforms. Experimental results show that the proposed TD3-assisted adaptive PI achieves constant-current (CC) regulation with significantly faster convergence compared to fixed-gain PI, settling time is reduced from 8.65 to 5.95 ms under aligned conditions, from 17.00 to 11.05 ms under lateral misalignment, and from 26.00 to 14.82 ms under angular misalignment, corresponding to improvements of about 35% and 43%. The faster transient response lowers stress and losses in the power switches. These results validate that DRL-enabled adaptive control enhances robustness of WPT-based LEV charging under realistic misalignment scenarios while remaining implementable on industrial-grade digital controllers.","PeriodicalId":13093,"journal":{"name":"IEEE Journal of Emerging and Selected Topics in Power Electronics","volume":"14 5","pages":"6821-6830"},"PeriodicalIF":5.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147684374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An inductor is integrated into the first H-bridge to boost voltage, while subsequent bridges are connected through inductors rather than switches. This topology effectively suppresses current spikes of capacitors, doubles DC voltages, and enhances output stability and gain. Taking a five-level topology as an example, the operating principle, mathematical model, and parameter design are analyzed, as well as the charging and discharging processes of capacitors. Concurrently, the soft-switching operating states and power loss of the proposed inverter are calculated and evaluated, and its performance is validated through experiments. Experimental results confirm the inverter achieves a voltage amplitude gain of 4 and reduces reliance on capacitors. Furthermore, most switches achieve zero-voltage switching (ZVS), significantly minimizing switching loss. The proposed inverter maintains high efficiency across a 0–1 kW range, peaking at 93.3%, with a total harmonic distortion (THD) as low as 17.06%.

By identifying the critical noise propagation paths, the drive power supply configuration of the auxiliary converter is optimized, thereby increasing the CM impedance along key paths and suppressing interference through noise cancellation principles.
