Cryogenically-Cooled Stabilized Power Factor Correction Rectifier for Future Aircraft Electrical Systems

The concepts of more or fully electric aircraft involve the use of superconducting technologies in conjunction with semiconductor power converters. In this case, the converters can be built into the common cryogenic system. This solution can lead to a significant improvement of the efficiency and power density of electrical system. At the same time, it requires taking into account important design features. This article presents the design of a stabilized power factor correction rectifier with cryogenically-cooled power stage. The results of simulation computer modeling and the design of the converter are demonstrated. The design features of the power stage are considered. The problem of the neutral current is also described. The developed PFC rectifier was assembled and tested. A comparison of the results of simulation computer modeling and the results of experimental studies is given. The results of the experimental studies verify the functionality of the converter, as well as the correctness of simulation computer models.
