Diagnostics and Fault Tolerance in DC-DC Converters and Related Industrial Electronics Technologies

Dear Colleagues,

The deployment of DC energy systems is an attractive alternative to conventional AC-based energy distribution systems, improving the efficiency of energy supplies and promoting renewable energies. Within DC energy systems, industrial electronics and particularly DC–DC converters are the key technologies that establish the interface between the multiple individual units of DC energy systems. Semiconductors and electrolytic capacitors, as critical components of DC–DC power converters, are particularly susceptible to suffering faults, which have a critical impact on converter operation. The implementation of diagnostic, prognostic, and fault-tolerant strategies, which are able to effectively deal with the multiple failure modes prone to occurring in DC–DC converters, is a challenging goal and is yet to be fully achieved. Accordingly, novel advancements in the diagnostics, prognostics and fault tolerance of DC–DC converters and related industrial electronics technologies require further attention.

This Special Issue focuses on the discussion of emerging solutions suitable for leveraging the availability, reliability, and robustness of DC–DC industrial power electronics technologies. Potential topics include, but are not limited to:

- Fault diagnostics and prognostics in DC–DC converters;
- Fault analysis in DC–DC converters;
- Fault-tolerant DC–DC converter topologies;
- Optimized control strategies for enhanced fault tolerance;
- Reliability predictions and the physics of failure of DC–DC converters;
- Thermal analysis of fault-tolerant DC–DC converters;
- Efficiency analysis and improvement of fault-tolerant DC–DC converters;
- Applications for fault-tolerant DC–DC converters (renewables integration, LED lighting, EV charging, etc.);
- Fault diagnostics in sensors;
- Reliable wide-bandgap technologies.
