On the study of the interleaving technique using an interphase transformer considering the use of SIC

Abstract

This paper compares the classic bidirectional boost converter with the interleaved boost one using an interphase transformer. A loss analysis considering the use of silicon carbide switches is performed considering two different scenarios: same number of commutations for both converters and same volume of magnetic cores. In both cases, the total silicon area is considered to be equal. The study shows that the structure using the interleave technique presents smaller losses, even when the same magnetic volume is maintained.
