Proton Exchange Membrane Fuel Cell (PEMFC) is one of the most promising technologies for sustainable energy production due to the high power density, low operative temperature and more convenient use for several applications. Nevertheless, the high generated current that characterizes PEMFC requires a specific power conditioning. In addition, specific controller must be designed to fit with system...
This paper presents a comparative study between rule-based and frequency separation energy management strategies within hybrid electric vehicle, using a Fuel cell (FC) as an energy source, and batteries as power source. FC supplies the main energy while battery supplies power peaks for fast acceleration and captures the braking regenerated energy. In this paper, we have shown the advantages and the...
According to innovation in grid connected transportation industry and with ever increasing concerns on environmental issues and clean energy, electric vehicles (EVs) and hybrid electric vehicles (HEVs) with low noise, zero emission, and high efficiency have attracted more and more attention of researchers, governments and industries, they are becoming the most likely fleets to replace gasoline vehicles...
The Proton Exchange Membrane Fuel Cell (PEMFC) is being investigated as an alternate power source for various applications as transportation and emergency power supplies. Fuel cell systems are characterized by high costs and complex auxiliary devices. For this reason, a fuel cell emulator can be used as a suitable and economic alternative to a real one for developing and testing a fuel cell power...
In this paper, a comparison between continuous and discontinuous space vector PWM control of six-phase VSI fed a double-star induction motor drive (DSIM) is presented. The induction machine has two sets of three-phase stator windings spatially shifted by 30 electrical degrees. Each set of three-phase stator windings is fed by a three-phase inverter. The harmonic characteristics of the VSI feeding...
The major drawback of usual dual three-phase AC machines when supplied by a voltage source inverter (VSI), is the occurrence of extra harmonic currents. These extra currents circulate only in the stator windings and cause additional losses. One solution to reduce their amplitude is to act on the supply side using dedicated PWM control strategies. In this paper, we present a direct torque control technique...
