Special Issue Information
Dear Colleagues,
The ever-increasing development of renewable energy sources (PV, wind, fuel cell, etc.) requires innovative power converter solutions to increase the efficiency of conversion. Multilevel power converters (MPC) have attracted increasing attention from academia and industry thanks to the advantages they bring, such as low harmonic content on the output voltages, low voltage stress, reduction of the EMI problems, etc. Nevertheless, these technologies require complex topology structures and hard control strategies. Moreover, single-stage converters based on an impedance source (Z-source) allow increasing the efficiency with respect to traditional solutions. In this context, impedance source multilevel converters inherit the advantages of Z-source converters (i.e., high-voltage boost capability, high reliability) and MPC (i.e., low harmonic content, low-voltage stress).
On the other hand, wide-bandgap (WBG) semiconductor devices, such as silicon carbide (SiC) and gallium nitride (GaN), provide significant benefits in comparison with the conventional devices based on silicon (Si) as far as power converter applications are concerned. It is well known that although SiC-based switching devices generally offer higher voltage ratings with respect to the GaN-based devices, they can lead to higher power losses. Due to the several opportunities provided by WBG in terms of converter performance improvement, these emerging technologies of switching power semiconductor devices can bring significant advantages to MPC, such as higher flexibility and wider ranges of power levels.
In order to promote further research and development of MPC based on WBG devices, the aim of this Special Issue is to provide a common environment for discussion, presentation of innovative solutions, and exchange of ideas among expert researchers in this field. The contributions can also include refinements on existing techniques, comparison between different solutions and economic analysis. Moreover, the experimental tests are necessary to validate the proposed solutions.
Topics of interest include, but are not limited to the following:
- Innovative topologies of MPC
- Innovative modulation techniques for MPC
- New control strategies for MPC (sliding mode, predictive control, sensorless, fuzzy logic, etc.);
- Emerging technologies of switching power devices, such as WBG, applicable to MPC
- Reliability analysis
- Efficiency analysis
- Review and last improvements on MPC
- Applications of MPC in renewable energy and grid-connected, such as in the following:
- PV systems
- Fuel cell systems
- Wind turbine systems
- Hybrid Energy Storage Systems
- Applications of MPC in automotive, such as the following:
- Battery management systems
- Vehicle-to–Grid
