Special Issue Information

Dear Colleagues,

The increasing penetration of renewable energy sources in the market, the growing demand for electric mobility, and the modernization of power systems are driving the development of advanced power electronics technologies. Power electronics converters are at the core of these transformations, enabling efficient energy conversion, grid integration, and the deployment of smart, flexible, and resilient power networks. Recent advances in semiconductor devices, control strategies, and digital technologies have opened new opportunities for improving the performance, reliability, and efficiency of these systems.

This Special Issue, "Advances in Power Electronics Converters for Modern Power Systems", aims to provide a platform for researchers and engineers to share innovative solutions, methodologies, and applications that address the evolving challenges of energy conversion. The topic aligns closely with the scope of Electronics, covering cutting-edge developments in power electronics, control systems, energy conversion, and smart grid integration.

We welcome both original research articles and comprehensive reviews. Potential topics include but are not limited to

  • The advanced topologies of inverters and converters for renewable energy integration.
  • High-efficiency and high-power-density designs for modern grids.
  • Wide-bandgap (SiC, GaN) device applications in power systems.
  • Control and modulation strategies for grid-tied converters.
  • Power electronics for electric mobility and charging infrastructure.
  • Fault-tolerant and resilient converter designs.
  • Modeling, simulation, and digital twin approaches for converters.
  • Energy storage interfaces and hybrid system integration.
  • Grid-supportive functionalities (voltage/frequency regulation, inertia emulation).
  • Smart grid and microgrid applications of power electronics converters.

We look forward to receiving your contributions.

Abstract
The central adjustment coil of a gasdynamic Electron Cyclotron Resonance (ECR) ion source requires wide-range bipolar current regulation over ±100 A with flat-top stability within 0.1% (1000 ppm) and a current rise time below 4 ms. Conventional fully controlled H-bridge converters operating under [...] Read more.
The central adjustment coil of a gasdynamic Electron Cyclotron Resonance (ECR) ion source requires wide-range bipolar current regulation over ±100 A with flat-top stability within 0.1% (1000 ppm) and a current rise time below 4 ms. Conventional fully controlled H-bridge converters operating under hard-switching conditions are unable to satisfy these requirements simultaneously, as the switching loss penalty restricts the control bandwidth and degrades flat-top stability. This paper presents an Asymmetrical Half-Bridge Flyback (AHB-Flyback) converter specifically designed for this application. By incorporating a dedicated resonant branch Lr–Cr on the primary side, the converter achieves primary-side Zero-Voltage Switching (ZVS) and secondary-side Zero-Current Switching (ZCS) over the full operating range, enabling 100 kHz operation without incurring the switching losses that would otherwise limit control bandwidth. A decoupled energy management architecture is adopted in which the primary circuit pre-charges an energy storage capacitor during idle intervals, and the coil current is subsequently established through an autonomous capacitor-to-coil discharge, effectively decoupling the peak power demand from the upstream supply network. The operating modes of the flat-top maintenance stage are analyzed through time-domain state equations, yielding an explicit closed-form expression for the Mode 3 duty cycle DT3. This expression demonstrates that DT3 is determined solely by the switching frequency and circuit parameters, independent of the load current setpoint, which is the fundamental mechanism enabling stable wide-range current regulation without parameter re-tuning. Parameter selection guidelines are derived from this result. Simulation results across the 20–100 A operating range and experimental validation on a scaled prototype confirm flat-top current stability within 1000 ppm and a current rise time of 4 ms, demonstrating the suitability of the proposed converter for precision ECR ion source power supply applications.

Despite the growing adoption of hybrid energy systems integrating solar photovoltaic (PV), pumped storage hydropower (PSH), and battery energy storage (BES), comprehensive studies on their dynamic stability and interaction mechanisms remain limited, particularly under weak grid conditions. Due to the high impedance of weak grids, ensuring stability across varied operating scenarios is crucial for advancing grid resilience and energy reliability. This paper addresses these research gaps by examining the interaction dynamics between PV, PSH, and BES on the DC side and the utility grid on the AC side. The study identifies operating-region-dependent instability mechanisms arising from negative incremental resistance behavior and weak grid interactions and proposes a virtual-impedance-based active damping control strategy to suppress poorly damped oscillatory modes. The proposed controller effectively reshapes the converter output impedance, shifts unstable eigenmodes into the left-half plane, and improves phase margins without requiring additional hardware components or introducing steady-state power losses. System stability is analytically assessed using root-locus, Bode, and Nyquist criteria within a developed small-signal state-space model, and further validated through large-signal real-time simulations on an OPAL-RT platform. The main contributions of this study are threefold: (i) a comprehensive stability analysis of a utility-scale grid-connected hybrid PV–PSH–BES system under weak grid conditions, (ii) identification of operating-region-dependent instability mechanisms associated with DC–link interactions, and (iii) development and real-time validation of a practical virtual-impedance-based active damping strategy for enhancing system stability and grid integration reliability.
