   ULTRACAPACITOR BASED BIDIRECTIONAL DC-DC CONVERTER PROTOTYPE FOR RECOVERY OF THE BRAKING ENERGY IN EV MOTOR DRIVES
By A. Di Napoli; F. Caricchi; F. Crescimbini [View]
[Download]

Abstract: This paper presents the experimental study of a bidirectional buck-boost dc-dc converter topology intended for use in electric vehicle drives. Such a converter arrangement allows the adjustament of the motor supply voltage during motoring operations and the control of the motor braking current for the recovery of the vehicle kinetic energy in an ultracapacitor tank. The paper discusses modes of operation of the proposed converter topology and reports experimental results taken from a prototype which was constructed using IGBT modules rated 600 V, 100 A and a tank of ultra capacitors each rated 470 F, 2.3 V.

   CARTESIAN FLUX OBSERVER FOR AN INDUCTION MACHINE: APPLICATION TO A ROBOT PROPULSION SET
By A. Bouscayrol; M. Delabre; M. Pietrzak-David; B. de Fornel; R. Bischoff [View]
[Download]

Abstract: A determinist flux observer for an induction machine is proposed in the fixed stator frame, with a decomposition of two sub-systems in each axe. An analytic study leads to a good estimation of these state variables. So, the flux components are utilised for a vector control of the induction machine. A mobile robot propulsion is chosen to validate this control structure, which allows reducing calculation time. Then experimental results are presented.

   PRELIMINARY DESIGN OF A 18 KV LOCOMOTIVE

Abstract: In this paper the authors look at the technological solutions just to convert and transform the 18 KV feeding supply voltage on locomotive board for the traction motors.

   MULTISYSTEM PROPULSION CONCEPT ON THE BASIS OF THE DOUBLE STAR CIRCUIT
By K. H. Ketteler [View]
[Download]

Abstract: With the double star circuit configuration a direct inverter off 3000 V dc line is realized without intermediate power conversion. It consists of standard 2-level converter modules which can be regrouped for all major line voltages, e. g. in multisystem traction vehicles. The overall system and operational advantages are presented and compared to conventional concepts.
