Comparison of Military Handbook and the FIDES Methodology for Failure Rate Estimation of Modular Multilevel Converters

Power electronics converters are crucial for power generation, transmission, and distribution. The modular multilevel converter (MMC) is highly valued for its ability to handle high power levels, versatility in reconfiguration, high efficiency through small-capacity submodules (SMs), and robust control capabilities. A failure of a power...

Switch Voltage Rating Selection Considering Cost-Oriented Redundancy and Modularity-based Trade-offs in Modular Multilevel Converter

Modular Multilevel Converters (MMCs) find increasing applications in medium to high-voltage systems. In such systems, reliability-oriented selection of power electronic switches becomes essential because higher modularity implies an increased number of components. The trade-off between the impact of higher modularity on converter reliability...

Restructuring medium voltage distribution grids: Parallel AC-DC reconfigurable links

Energy transition will inevitably lead to greater electrification. For example, it is anticipated that electrical energy demand will rise by at least 2-3 times by 2050 with increasing share of electric vehicles and heat pumps. This will translate to significant increase in power demand on the existing medium voltage distribution grid, resulting...
