“…According to Figure 15, at t = [0, 1] s corresponds to the transient regime. An acceleration is applied at the different times t = [1,5,4,7,9,11] s and a deceleration at the times [3,6,8,10,12] s. During acceleration, it is the battery and the fuel cell which intervene to give the power required by the load. During deceleration, the fuel cell begins to charge the battery and there will also be energy recovery due to braking and this in the form of potential energy.…”

The aim of this paper is the developments a DC/DC boost converter use to powered a DC/AC inverter with induction motor. A strategy of control of an induction motor (IM) used as a propulsion system of an electric vehicle (EV). The boost converter ensures an energy flux for an ideal operation of the vehicle even in case of battery voltage drop. The technique proposed is based on a direct flow and torque control diagram (DTC) and also introduces the fuzzy logic control (FLC) as well as the regulator in the place of a conventional PI regulator. The proposed approach covers the vehicle's torque demand and it optimizes the training performance. Simulation results on a test vehicle propelled by 38-kW induction motor showed that the proposed control approach operates satisfactorily. The analysis and simulations lead to the conclusion that the proposed system is feasible and can be tested on experimental bench.

At present, about nineteen resonant compensation networks capable of operating as pulsating voltage source are utilized for wireless power transfer (WPT), in which all resonant elements participate in resonance. The majority of networks employ full-bridge or half-bridge topologies which suffer from significant stray and leakage inductances that trap the energy and limit the power transfer; hence, reduce the efficiency. Therefore, these topologies utilize additional resonant networks with many elements and switches to exploit all magnetic field-flux density curve quadrants to eliminate switching losses. Such an approach is less desirable as it adds cost and increases complexity. Therefore, this paper proposes four DC-DC converters that utilize resonant compensation networks without additional resonant tanks, targeting Electric Vehicles wireless charging applications. The proposed converters meet the requirements of charging time, cost, range and high efficiency without a dc flux bias as in existing solutions. The technical viability of the proposed dedicated dc-dc converters for wireless power transfer applications has been validated using preliminary simulations.

“…For isolated DC-DC converters high voltage transformers (HVT) are utilized as presented in [4,[20][21][22][23][24][25][26]. Typically, for such converters high gain voltage boosting can be attained by HVT with high turn's ratio and by using voltage multipliers [16,[27][28][29][30]. Considering the case of full-bridge converters based on Phase-Shifted (PS) PWM, Zero-voltage (ZVS) and Zero-current (ZCS) switching can attained by utilizing leakage inductance of the HVT.…”

In this paper, a comparative analysis has been presented on various topologies of isolated and non-isolated DC-DC converters. Here, the major focus remains on transformer-less (TL) DC-DC converters, based on the conventional basic boost converter. In addition, to attain high voltage gain, a classification of non-isolated converters based on extendable and non-extendable design has been presented. For comparative and theoretical analysis, the parameters chosen are the number of components utilized by each converter topology, high voltage gain offered, voltage stresses on each component involved and the efficiency of the high gain topologies. For the converters under discussion, operation under ideal and non-ideal conditions has also been highlighted. Based on this study, authors present a guide for the reader to identify various high voltage gain topologies for photovoltaic (PV) systems.
