   3kV refurbishment chopper designed with 6.5 kV IGBT
By J.M. Bodson; A. Colasse; J.E. Masselus; D. Zorzynski [View]
[Download]

Abstract: In the 3kVDC catenary countries where the operator is concerned about its old designed rolling stock (camshaft system or thyristor chopper feeding DC motors), a 3kV IGBT Chopper can be proposed to replace the electrical propulsion system. Up to now, the 3kV IGBT chopper could be designed with 3.3 kV or 4.5 kV IGBT used in 3-level schemes (e.g. : imbricated cells) or in 2-levels schemes (e.g. : direct serial connection with active clamping). The coming of the 6.5 kV IGBT permits to design 2-levels converters directly connected to the 3kVDC catenary with no need of serial connection. This paper presents the development of a chopper based on the 6.5kV IGBT module.

   A Novel BeatlessControl for AC Electric Cars.
By S. Inarida; T. Tanamachi; K. Nakata [View]
[Download]

Abstract: In power converter systems for AC electric cars, the DC link voltage contains a ripple component because of the single-phase voltage source. Therefore, a beat phenomenon of the motor current occurs, which causes torque ripple and a howling noise of the motor. A solution to this problem is use of an additional series resonant filter at the DC link. However, addition of another component is an obstacle to making the power converter system smaller and lighter. This paper proposes a novel beatless control, based on the frequency modulation and vector control, which can effectively suppress the beat phenomenon without using an additional resonant filter at DC link. Effectiveness of the control is demonstrated with simulation and experimental results.

   Behaviour model control structures for an electrical vehicle
By J. Pierquin; B. Vulturescu; A. Bouscayrol; J.P. Hautier [View]
[Download]

Abstract: A specific formalism based on energetic conversion is used to model an electric vehicle using two DC motors. From this modelling, a complete model of the electromechanical system is implemented in simulation: this model includes both DC motors, the wheels and vehicle dynamics induced by the adhesion phenomenon. Several anti-slipping controllers based on Behaviour Model Control (BMC) structures are proposed to overcome the non linear problem of adhesion. Simulations point out the efficiency of these structures. Results, which are given for several wheel-road surface conditions, are reported and described.

   Challenges and limitations of All Electric Ship Designs
By A.J. Blokland; E. van Dijk [View]
[Download]

Abstract: Enhanced safety requirements and tight economical benefits influence the merchant ship design. Life cycle costs, survivability aspects and robust design play an important role in naval architecture for the Royal Netherlands Navy (RNlN). New developments in power electronics and drives make it possible to improve the reliability of the platform and reduce life cycle costs of new ship designs. The impact in the ship design is evaluated by replacing the conventional energy system by new All Electric Ship (AES) concepts. Following lessons learned during the design and commissioning of the integrated electrical system of the PLD HNlMS Rotterdam and new hydrographic vessels a comparative analysis of the stability, EMC and load management in electrical distribution configurations is given. This paper presents a survey of the influence on reliability, life cycle costs and technical consequences applying power electronics in electrical energy naval ship system designs.

   Damping control strategy for the vector controlled traction drive
By B-H. Bae; B-H. Cho; S-K. Sul [View]
[Download]

Abstract: This paper describes the control aspects of the 1.2 MVA IGBT traction drive for transit car. In case of traction drive, the input LC filter is located between the inverter and the pantograph terminal in order to reduce the ripple current from the supply current and harmonic current from the inverter. And the vector controlled inverter with high power density and fast torque response acts like a negativeresistance to the input LC filter and causes the resonance and instability. So the high performance vector control strategy for traction drive requires an effective control algorithm to stabilize the resonance of input LC filter. In this paper, the instability problem of the filter is investigated and an effective damping algorithm for vector controlled traction drive is proposed. And to prove the validation of the proposed control, the experimental results, performed on Seoul metro line using real transit cars with 1.2MVA IGBT inverter systems, are presented.

   Matching Analysis of Wound Field Rotor Synchronous Motor to its Supply
By P. Mestre; S. Astier [View]
[Download]

Abstract: This paper describes the matching analysis of wound field rotor synchronous motor to its supply for electric vehicle application. The limitation of the voltage and the current supply require an operating field weakening of the machine above base speed. Analysis shows the advantage of having a field weakening by action on the inductor current compared to field weakening controlling the flux direct component of the armature reaction. In this study, we consider no saturation effect, e.m.f and sinusoidal current and a airgap flux density. Then, we show that the number of conductors per slot according to the application is an important choice. In our study, we considered the electric vehicle application. Finally, the simulation is given to quantify the effect of the number of conductors per slot on autonomy.

   Sensorless Speed Control of Slip-ring AC Motor
By F. Kolonic; T. Idžotiæ [View]
[Download]

Abstract: Sensorless speed control system with slip-ring AC motor is a highly developed, wellproven system for heavy duty tasks especially in the field of industrial cranes and another heavy duty material handling systems. In situations where there is no tachometer or incremental encoder as a speed feedback devices, actual speed information is realized via rotor voltage frequency estimation (RVFE). Using line frequency as a reference, the fundamental component of the rotor frequency gives the slip of the motor, which determines the speed in digital form.

   Torque Control for a Single Phase Induction Motor
By J. L. Romeral; E. Aldabas; T. Arias; J. Llaquet [View]
[Download]

Abstract: Investigations were carried out on the control of the Single -Phase Induction Motor by means of a switched capacitor, which not only makes the starting torque of the motor better, but also improves the torque available in the overall speed range. The capacitor is shorted during each cycle to vary the effective size of the capacitance as indicated by tabulated data. The data were obtained from a theoretical expression, and they were later modified as desired by using an industrial motor workbench, to match them to every specific motor. The proposed system could be easily incorporated to any industrial equipment due to its simplicity and robustness.

   Transformerless Drive System for Main Line Rail Vehicle Propulsion
By S. Dieckerhoff; U. Schäfer [View]
[Download]

Abstract: Low frequency, medium voltage transformers in main line rail vehicles suffer from poor efficiency and high weight. Completely transformerless solutions were not up to now attractive due to the high motor and converter expenditures. To solve these problems, motors with a more medium voltage friendly winding structure as e.g. an induction motor with fractional slot winding are proposed. Based on the new 6.5kV IGBT, the feasibility of multilevel converter topologies as the diode clamped converter and the flying capacitor converter is analysed. The paper gives an evaluation of drive concepts combining motor and converter properties. A solution with 4 series connected drives turns out to be the most favourable solution.
