Representative work: The dc circuit breaker is an indispensable building block for dc network systems. Hybrid circuit breakers that combine mechanical and solid-state switches have more potential to be utilized in dc distribution networks because of their lower conduction losses and fast interrupt speed. The efficient energy dc interrupter with surge protection (EDISON) removes any solid-state circuit in the main current path, thereby substantially reducing the conduction losses during normal operations. However, it requires a dedicated control with fast dynamics because any false triggering of the mechanical switch or solid-state switches of the breaker would lead to a commutation failure and a potential unquen We propose a thermally efficient and power-dense high-temperature superconducting (HTS) cable (CLEAN Cable) as well as a thermally efficient, mechanically rugged, and easily attachable/detachable cryogenic-to-ambient power link (CLEAN Connector). The bundled design enables high gravimetric power density and node-less tapping of power. The CLEAN Connector minimizes ambient heat leaking into the cryogenic environment by magnetically coupling the cryogenic section to the ambient counterpart via a high-frequency isolated DC/DC converter. The proposed high-frequency operation reduces the core size of the cryogenic/ambient transformer that provides electrical and thermal isolation while enabling q
