In such systems, interleaved switching can be employed to improve output waveform quality, reduce filtering requirements, and lowering the size of magnetic components. When compared to using pulse width modulation (PWM) switching patterns with fixed phase-shifts between parallel inverter leg outputs, continuous PWM switching using dynamic phase-shifting has been shown to yield a higher-quality multilevel output. Discontinuous PWM (DPWM) techniques reduce switching losses, but existing interleaved DPWM methods are limited to fixed PWM phase-shifts between parallel outputs. The challenge for using DPWM switching together with dynamic phase-shifting remains in eliminating dc offsets in circulating currents due to phase-shifting and sector transitions. These dc offsets increase system losses and coupled inductor (CI) flux, over-sizing the CI design, and raise stability concerns. Therefore, reference signal manipulation techniques are described that use a common carrier for PWM synchronization to achieve: dynamic phase-shifted DPWM (DPS-DPWM) that produces high-quality multilevel line voltages at the output of the parallel system; half-carrier cycle transition control that avoids generating dc offsets during reference signal zero crossover regions and sector changes in the DPWM. The described PWM scheme is experimentally validated using a 3.3 kW (300 <inline-formula><tex-math>$V_{dc}$</tex-math></inline-formula>, 180 <inline-formula><tex-math>$V_{ac,rms}$</tex-math></inline-formula>) SiC-module-based laboratory setup with two paralleled 2L-VSCs connected to an ac grid.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"409-424"},"PeriodicalIF":3.9,"publicationDate":"2026-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11359494","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175876","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 review provides a structured synthesis of the existing literature on GFM inverters, with emphasis on control philosophies, stability perspectives, and conceptual frameworks that guide their application. It further discusses emerging themes such as the integration of Artificial Intelligence (AI) and Digital Twins (DTs), reflecting their growing relevance in shaping. future research directions.

The method enables continuous power control without changing the switching frequency, duty cycle, or phase shift, making it suitable for DC transformer architectures that normally operate in a load-independent manner. A modified cycle-skipping approach is introduced to maintain magnetizing current during idle intervals, thereby preserving soft switching across the full operating range. The sigma–delta modulator replaces the fixed burst patterns of traditional cycle skipping with a noise-shaped pulse distribution that improves control resolution and mitigates low-frequency ripple. A practical implementation on an STM32 microcontroller is presented, including a lookup-table-based mapping of the sigma–delta bitstream to hardware burst-mode registers. Experimental validation on a 1-kW SRC-DCX prototype confirms accurate power regulation. Later demonstrated that, when extended to a dual-module IPOP configuration, the method achieves effective current balancing, with a peak efficiency of nearly 98%.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"439-448"},"PeriodicalIF":3.9,"publicationDate":"2026-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11355809","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175908","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 key novelty lies in the proposed algorithm capability to ensure compliance with EN 50160 and IEEE Std 1547-2018 standards even under low-switching frequency conditions, without requiring a fixed switching frequency and symmetrical voltage waveform, typically guaranteed by a devoted modulation stage, and without oversizing the LCL filter. To achieve this goal, a multi-term cost function is designed to regulate inverter-side currents, capacitor voltages, and switching effort. For control validation, comparative analysis between the proposed strategy and the phase-shifted pulse width modulation-based voltage-oriented control is conducted at the same average switching frequency. Results show that only the proposed control strategy meets the grid standard requirements. Furthermore, the proposed FCS-MPC maintains standard compliance while further reducing the switching frequency, thus outperforming the voltage-oriented control. Finally, the proposed strategy exhibits intrinsic active damping capability and guarantees superior steady-state and dynamic performance compared to standard active damping strategies in the literature.","PeriodicalId":93182,"journal":{"name":"IEEE open journal of power electronics","volume":"7 ","pages":"475-502"},"PeriodicalIF":3.9,"publicationDate":"2026-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=11344747","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146175885","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}

By incorporating clamping capacitors and additional inductors into the buck converter topology, the proposed design achieves a significantly higher step-down conversion ratio while reducing voltage stress and improving efficiency. In the proposed converter, the clamping capacitors store energy to act as a voltage source, thereby reducing voltage stress on the switching devices. While the main inductor serves as the primary component for energy transfer to the output, additional inductors are connected in parallel to reduce the burden on the clamping capacitors, reduce current stress, and ensure natural balance. Furthermore, the switch network is scalable to achieve the desired voltage conversion ratio, depending on the application.
