A novel efficient boost chopper integrated with two cryogenic metal-oxide semiconductor field-effect transistors (MOSFETs) and one high-temperature superconducting (HTS) inductor is presented. State-of-the-art CoolMOS MOSFETs are introduced and immersed in liquid nitrogen to save about 85% of conduction losses. Considering the anisotropy of gadolinium barium copper oxide (GdBCO) tapes, ferromagnetic...
Cryogenic operation of power electronics provides many promising benefits for power conversions compared to their ambient-temperature counterparts. This paper presents a cryogenic boost-buck chopper integrated with cryogenic MOSFETs and high temperature superconducting (HTS) inductor. The results obtained show that the proposed boost-buck chopper has much higher operational efficiency than the conventional...
