Research Institution
Recent advances in the area of high temperature superconductors have opened the door to the possibility of developing highly efficient low-temperature power electronics. The most commonly used high-efficiency capacitors are based on high dielectric constant (K ~ 1000-4000) BaTiO3 doped to yield an X7R temperature dependence (±15% change in capacitance from -55C to 125C), but below their minimum use temperature the capacitance drops-off quickly leading to a low volumetric efficiency. In this program TRS Technologies and The Pennsylvania State University propose to develop improved dielectric materials with properties optimized for cryogenic operation. The feasibility of these new dielectrics for use at cryogenic temperatures will be demonstrated by testing in a cryogenically cooled power circuit.
