   Simulation and design of a hybrid vehicle: failure and safety management
By K. El Kadri, A. Djerdir, A. Berthon [View]
[Download]

Abstract: This paper proposes to study an experimental series hybrid heavy vehicle (ECCE) which power system consists on two generator units: the first one (diesel ICE + alternator MT1-AL1) is of 80kW of power and it works at a constant speed and the second one (diesel ICE + alternator MT2-AL2) having 80kW of power works at a variable speed mode. Both units supply a DC bus for which the voltage is fixed at 540V (±270V) by a pack of batteries (BAT). This 12 tons electric truck has four independent driving wheels (4x30kW) supplied from the DC bus through four inverters. This paper will focus on safety and failure management.

   Battery parameters adjustment for series hybrid bus by simulation
By Antoni Szumanowski, Chang Yuhua, Piotr Piórkowski [View]
[Download]

Abstract: Hybrid electric vehicle (HEV) is one of remarkable solutions for world wide environmental and energy problem caused by automobiles. The research and development of various technologies in HEV are being actively conducted in the world. Series hybrid bus is a good solution for decreasing downtown air pollution. This paper presents two different control strategies of series hybrid bus and battery parameters adjustment by simulation. The paper compares fuel consumption of series hybrid bus with conventional bus. The fuel consumption of series hybrid bus before and after adjusting battery parameters and engine operating points are also compared.

   Performance Analysis of Four-Leg VSC under Unbalanced Load Conditions for Hybrid Power System Application
By I. Vechiu, H. Camblong, O. Curea, B. Dakyo, G. Tapia [View]
[Download]

Abstract: In this paper, the transient operation of four leg voltage source converter (VSC) under unbalanced load conditions is investigated. The inverter is particularly interesting for simultaneous supply of three phase and single phase load in transformerless Hybrid Power System (HPS) application. A control strategy for the VSC based on the decomposition of the supply voltages and currents into instantaneous positive, negative and homopolar sequence components is described. The three sequences are controlled using two different rotating reference frame systems, so that the disturbance of the output voltage due to the load unbalances is eliminated. Simulation results are presented to verify the transient operation of the VSC under unbalanced load conditions.

   Fuzzy Control of Bi-directional DC-DC Converters in Hybrid Fuel Cell / Battery Power Source
By Mahshid Amirabadi, Shahrokh Farhangi [View]
[Download]

Abstract: Hybrid fuel cell / Battery power source is one of the essential parts in fuel cell vehicles. Usually a bi-directional DC/DC converter is placed between the fuel cell and the battery. The control of this converter has an important role in the system performance. In this paper fuzzy control is applied to the bi-directional DC/DC converter. Simulation results show that this method has a good dynamic performance.
