“…In order to reduce the reluctance, ferromagnetic material is usually used to concentrate the flux lines in practice [26]. As a result, the self-inductances of the primary and secondary coils change slightly when the relative position of the primary and secondary sides changes [26,27].…”

This paper compares the characteristics of the series-series (SS) and double-sided LCC compensation topologies for electric vehicle (EV) wireless chargers. Both the well-tuned and mistuned topologies for the two compensation methods are analyzed in detail. The mistuning considered here is mainly caused by the variations of the relative position between primary and secondary sides. The output power displacements (PD) caused by mistuning are compared for both compensation topologies, as well as the impacts of the load variations on the performances of the mistuned topologies. The voltage and current stresses on components are also studied. The comparative result shows that the double-sided LCC compensation topology is less sensitive to the mistuning. A double-sided LCC compensated EV wireless charger system with up to 7.7kW output power is built to verify the analysis results. A peak efficiency of 96% from DC power source to battery load is achieved.

“…Mathematically, the selection of the secondary capacitance can be expressed in terms of the capacitive reactance associated with the capacitor, X c2 and the inductive reactance associated with the secondary leakage and the mutual inductance (X l2 and X m ) as: (13) This would further imply that the capacitance of the secondary compensation capacitor (C 2 ) is related to the resonant angular frequency of the secondary circuit (ω 0 ) as: (14) The above relation would remain the same independent of the type of capacitor connection to the secondary. This is followed by the design of the primary circuit compensation capacitance.…”

“…The designed system has to be simulated as closely as possible to its effective behavior for a successful conclusion of the overall design process. In the literature, load modeling is a widely addressed topic [19]. In [8], a digital still camera has been modeled by reproducing the power consumption profile of each available function.…”

In this paper, fuel cellbased hybrid power supplies for household appliances are addressed. The profile of residential power consumption is evaluated during working, non-working days in both summer and winter periods. The worst-case load power demand is therefore highlighted. A 5kW Nuvera PowerFlow proton exchange membrane fuel cell for household appliances is tested. On the basis of the characterization of the fuel cell stack under test, stand-alone and fuel cellbattery active hybrid power supply architectures are both considered. Experimental validation of three power management algorithms is proposed in terms of hydrogen consumption, cost and energy saving. Power management algorithms are validated by the mean of experimental data in MATLAB environment.Index Terms-fuel cells, hybrid power systems, power system control, power supplies.
