—This paper proposes a strategy to minimize the losses of an induction motor propelling and Electric Vehicle (EV). The proposed control strategy, based on a Direct Flux and Torque Control (DTC) scheme, utilizes the stator flux as control variable and the flux level is selected in accordance with torque demand of the EV to achieve the efficiency optimized(More)
—This paper presents system modeling, analysis, and simulation of an electric vehicle (EV) with two independent rear wheel drives. The traction control system is designed to guarantee the EV dynamics and stability when there are no differential gears. Using two in-wheel electric motors makes it possible to have torque and speed control in each wheel. This(More)
In this paper, a new method for the detection of electrical arc faults is presented It is possible, by using a digital signal processor programmed with Matlab/Simulink, to create a system able to detect the presence of unwanted frequencies in the distribution network. Those frequencies are often generated by an electrical arc in the network.
The article aims to simulate a multipowered onboard drive train system. The proposed system is capable of managing and constantly adapting several power sources of different characteristic to a varying current load. All the power sources integrated in the onboard drive train are renewable energy. They include a battery bank, supercapacitors and a fuel cell.(More)
This paper presents a new simple dynamic Lithium-Ion battery model. It is modelled by MATLAB/Simulink and SimPowerSystems software packages and simulated at different temperatures, load current, and cycle life number. The interest of this model is the ability to study the behavior of this battery, and improve its life cycle. The model is simple and can be(More)
Several converter configurations have been proposed in literature to achieve fuel-cell power conversion systems. In this paper a new converter high frequency unidirectional DC-DC was proposed simulated and realized. This last one allows to obtain an output voltage is 550V from an input voltage of 28V (output voltage of fuel-cell). The control strategy used(More)
—The use of an Electric Differential (ED) constitutes a technological advance in vehicle design along with the concept of more electric vehicles. EDs have the advantage of replacing loose and heavy mechanical differentials and transmissions with lighter and smaller electric motors directly coupled to the wheels via a single gear or an in-wheel motor. This(More)
Fuel cell vehicles (FCV's) appear to be one of the viable solutions for the growing concerns for environmental protection and the fast rate of depletion of world oil supply. FCV's can become a viable alternative to the internal combustion engine only if they are able to meet certain reliability, safety, performance, and cost criteria. Improvement of(More)
Artificial intelligence techniques, such as fuzzy logic, neural network, and genetic algorithm, are recently showing a lot of promise in the application of power electronic systems. This paper describes the strategy development with a minimum losses algorithm under field-oriented control; this strategy is applied to improve high efficiency of the induction(More)
