United States Project Notice - Resonant Solid-State Breakers Based On Wireless Coupling In MVDC Systems


Project Notice

PNR 62473
Project Name Resonant Solid-State Breakers Based on Wireless Coupling in MVDC Systems
Project Detail Drexel University is proposing a solid-state MV circuit breaker based on silicon carbide devices, a resonant topology, and capacitive wireless power transfer that aims to significantly improve breaker performance for the MVDC ecosystem. The project combines innovations in using an active resonant circuit to realize zero-current switching, wireless capacitive coupling between the conduction and breaker branches to avoid direct metal-to-metal contact for rapid response speed, and wireless powering to drive the MV switches for improved system reliability. Potential Impact: The proposed breaker is installed close to loads to rapidly detect and react to the short-circuit fault. Thus, it could enable an increased number of electronic loads that operate using DC, such as ultra-fast electric vehicle charging stations and utility scale energy storage battery units, to connect to the MV distribution grid. This would improve overall power delivery efficiency.
