“…These resonant compensation circuits are shown and detailed in [23,24]. Non-isolated and isolated versions of Ćuk and SEPIC converter have been used in the literature [25][26][27][28][29][30]. Magnetically coupled single-switch buck-boost converters (namely isolated Ćuk, Zeta, SEPIC, and P5) have been presented in [1].…”

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.

“…In a fuel cell system, drawing discontinuous input current lead to higher hydrogen consumption, hence the efficiency of FC diminishes [17]. On the other hand, converters with continuous input current can operate more accurately around the maximum power point in a photovoltaic system [18]. Thus, it is noticeable that the efficiency of both FC and PV can be improved by utilizing converters with a continuous input current.…”

“…Thus, it is noticeable that the efficiency of both FC and PV can be improved by utilizing converters with a continuous input current. Besides drawing chopping input current from FC and PV has negative influence on their lifetimes [17,18]. Therefore, converters with continues input current are always attractive due to their reducing negative impact on the DC input source.…”

Y-source impedance network is a new topology intended for implementing with high voltage gain converters. In contrary to the original Y-source impedance network, an improved Y-source presented in this paper has the advantage of a continuous input current characteristic. Since achieving high voltage gain and continuous input current, converters employing the proposed impedance network are suitable for implementing with renewable energy sources like fuel cell and photovoltaic systems. In this paper, analysis and operation principles of the developed network have been discussed. Moreover, mathematical equations and input current ripple analysis have been demonstrated in detail. Finally, both computer simulations and experimental results from a boost dc-dc converter are presented to validate the performance of the developed network.

“…1 shows the influence of the voltage and current ripple on the power curve, where a weighty loss of power as the ripple rises. The photovoltaic cell characteristics change owing to the radiation and temperature, which decrease the average power hence increase the losses [4]. As ripple current raises the effective point transfers to the region of constant voltage on the photovoltaic characteristic curve, which outcomes in a sharp decline in the power.…”

AbstractÑThis paper discusses the impact of fill factor on the input current ripple of the photovoltaic module and the loss effect on power extracted. Photovoltaic moduleÕs P-V curve produces exponential curve. The curvature of this curve indicates the fill factor of the particular cell, hence, by increasing the fill factor, the available extracted power increases. Yet, this paper states that losses due to photovoltaic current increases by increasing the fill factor.
