Special Issue Information

Dear Colleagues,

High-power power electronic converters play a crucial role in energy and industrial systems. They possess applicative potential in a variety of domains, including the efficient integration of renewable energy resources, e.g., wind and solar, into grids and off-grid systems; the operation of power converters under challenging conditions such as weak grids; the fault ride through of power converters; electric vehicles and battery charging stations; industrial motor drives; uninterrupted power supplies; AC–DC microgrids; and high-voltage DC interconnections.

In order to serve these applications, numerous power electronic converter topologies have been designed; these include two-level voltage source converters, current source converters, Z-source converters, and multi-level converters. In addition, various controllers are employed in the control schemes, including grid-following and grid-forming controllers.

The objective of this Special Issue is to focus on high-power power electronic converters by (1) addressing their emerging applications and associated challenges, (2) improving their steady-state performance and dynamic stability response under different conditions, (3) proposing novel control algorithms for efficient and robust operation, and (4) improving the design of the power circuit.

In this Special Issue, articles that perform evaluations and verify results using offline simulations that are complimented by real-time simulations or circuit prototypes results are welcome.

The scope of this Special Issue includes the following topics.

  • Grid-following power converters.
  • Grid-forming power converters.
  • High-voltage DC interconnections.
  • Fast-charging vehicle stations.
  • Novel control algorithms for high-power power converters.
  • Novel converters power circuit schemes.

AC/DC converters, controlled by pulse width modulation (PWM) and used as power factor correction (PFC), is considered one of the main contributors to emissions in the range 2 kHz–150 kHz, recently known as the supraharmonic (SH) range. This study looks at the impact of SH grid distortion on the LF (<2 kHz) and HF (>2 kHz) emission of an AC/DC converter. The PFC boost converter is used as a particular case for validation of the results. It is observed that the AC/DC converters emit additional LF interharmonics and subharmonics when the grid voltage contains interharmonic components in the SH range. A mathematical analysis is provided to study and assess the interference between the SH in the background distortion and the AC/DC converters. Experimental studies are then performed for a PFC boost setup based on dSPACE MicroLabBox for the purposes of validating the mathematical analysis. Full article
