Abstract

The wireless charging of electronic devices, such as electric vehicles, is an alternative that promises comfort and convenience to the user. The resonant converters are an important alternative for the implementation of power conditioning circuits with an excellent density/power ratio, this backed by high efficiency and the possibility of switching the transistors to low currents and voltages. A limitation of the wireless charging systems of a resonant nature is the dependence between the parameters of the resonant filter and the power delivered to the load. In this work, a control alternative for a resonant DC-DC converter is presented. The simulation results validate the proposed hypothesis, in which the possibility of obtaining a DC-DC resonant converter operating at the maximum power predicted by the tank before variations in its parameters is manifested.
