Special Issue Information

Dear Colleagues,

Power electronic converters are indispensable components of modern energy systems and enable the required flexible energy conversion and transmission functions. Next-generation power electronic converters will inevitably exhibit higher power density, higher reliability, greater compactness, higher efficiency, and lower cost. To meet the challenges posed by the next-generation power electronic converter, new topologies, new magnetic design, advanced thermal design solutions, and the corresponding controls should be further researched. The main objective of this Special Issue is to collect the latest developments in novel topologies of power electronic converters, modeling and control for power electronic converters, magnetic components optimization and design, and thermal solution for power electronics converters.

Prospective authors are invited to submit original contributions for review and publication in this Special Issue. Topics of interest for publication include, but are not limited to:

  • Innovative topologies: soft-switching topology, bidirectional DC/DC converter with a wide voltage gain, high-frequency converter, etc.
  • New architectures: multiphase converters, multilevel converters, modular converters, partial converter, etc.
  • Modeling of power electronics converter.
  • Control strategies and parameter design.
  • Magnetic design for power electronic converters.
  • Thermal modeling, testing, and design.
  • Soft switching techniques.

Currently, most of the series inverter control methods rely on communication, which greatly reduces the reliability of the system and increases the cost. To address the above problems, this paper proposes a decentralized control strategy for series-connected single-phase two-stage grid-connected photovoltaic (PV) inverters. By improving the traditional droop control, the frequency and phase of the output voltage of each inverter unit are consistent and self-synchronized with the power grid while relying only on local independent control, and each unit realizes maximum power point tracking (MPPT). At different light intensities, each series-connected unit can quickly track the new maximum power point while still maintaining self-synchronization between the units. The system stability is analyzed via the small signal method, and sufficient conditions for system stability are obtained. Finally, the simulation results verify the correctness and effectiveness of the proposed control strategy. Full article
