Cryogenic Power Electronics

Superconducting power system efficiency suffers from heat influx from ambient if the power has to leave a cryogenic environment for power conversion before entering another superconducting device. A substantial share of the total heat leak is located at the interfaces between cryogenic devices and ambient temperature devices. Therefore, it is important to minimize the number of non-cryogenic power components. To do so, power electronic converters operating at cryogenic temperatures are required. This project investigates the feasibility of using power electronic devices in cryogenic environments.
