Special Issue Information

Dear Colleagues,

Resonant converters are a type of power electronic converters that use resonant effects to convert electrical energy with minimal losses and high efficiency. Due to their ability to operate at high frequencies and reduce electromagnetic interference, they are widely used in: industrial technologies; energy storage systems; decentralized power generation based on renewable energy; power supplies for sensitive consumers; and transportation. The basic idea for the implementation of resonant converters is the use of resonance between inductive and capacitive equivalent elements in the circuit, which allows these converters to operate at zero voltage and/or zero currents switching to increase the efficiency and power density.

The Special Issue aims to present the latest advances in the theory, design, modeling control and prototyping of resonant converters in various industrial applications.

Topics of interest for this publication include, but are not limited to:

  • Resonant Power Converters for Automotive Applications;
  • Resonant Power Converters for Wireless Power Transfer;
  • Resonant Power Converters for Energy storage systems;
  • Resonant Power Converters: Modeling and Simulation, Design and Control Method Optimization;
  • Resonant Converters for EV Charging Stations;
  • Resonant Converters for PV Applications;
  • Resonant Converters in Electrotechnology Equipment;
  • Resonant Converter for LED Lighting Applications;
  • Resonant DC-DC Converter for Solid State Transformer Applications;
  • AI based metods for Modeling, Design, Optimization and Control for Resonant converters;
  • Trends and Future in the Development of Resonant Converters;
  • Transformers and Passive Components for Resonant converters.

This study proposes an optimal resonant network design for an 11.1 kW wireless power transfer (WPT) system with a double-sided LCC compensation circuit, targeting 800 V class battery applications. Conventional WPT circuit topologies and design parameters specified in existing standards, such as SAE J2954, are unsuitable for 800 V class battery systems because they impose excessive voltage and current stresses on the resonant network components. To address this, the proposed design focuses on minimizing component stresses while ensuring compliance with the output voltage requirements for 800 V battery charging. A switched capacitor technique is integrated into the resonant network to dynamically adjust the compensation capacitance, enabling seamless adaptation to the constant current–constant voltage charging profile. The feasibility of the WPT system is validated through simulations and experiments, demonstrating an input voltage of 400 VDC, an output voltage range of 560–820 VDC, and a rated power capacity of 11.1 kW. Under rated conditions, the system achieves a peak efficiency of 95%, underscoring its practicality for high-voltage electric vehicle charging applications. Full article
