Reconfigured single- and double-diode models for improved modelling of solar cells/modules.

Proper modeling of PV cells/modules through parameter identification based on the real current-voltage (I-V) data is important for the efficiency of PV systems. Most related works have concentrated on the classical single-diode model (SDM) and double-diode model (DDM) and their parameter extraction by various metaheuristic algorithms. In order to render more accurate and representative modeling, this paper adds a small resistance in series with the diodes in SDM and DDM.

Design and application of wireless power transfer using Class-E inverter based on Adaptive Impedance-Matching Network.

Class-E inverter, which is assumed as an ideal exciter for wireless power transfer system due to their low power losses and suitability for high-frequency operation, can operate under the proper switching conditions when the distance between the transmitter and the receiver and the load is constant. The change in the distance between the coils or the load value removes the optimum switching conditions and causes high switching losses. This paper describes all design procedures and the inductive coupling wireless power transfer system based on a Class-E inverter used as a coil driver.
