Abstract:
COPPE/UFRJ develops a superconducting magnetic levitation vehicle (SML) named
MagLev-Cobra. The project began last decade with a small-scale prototype. Presently a
full-scale one is under construction. For traction, MagLev-Cobra uses a linear induction
motor (LIM) [1]-[2] patented by UFRJ [3] due to its innovative geometry that contributes
for the levitation. In this paper, the back-to-back converter used for the regenerative brak-
ing is presented. This converter allows the return of energy generated during deceleration
to the grid [4]. Results of the regenerative braking and DC braking for the linear induction
motor are discussed.
