Regulating the load voltage is of major importance for ensuring high transmission efficiency in wireless power transfer (WPT) systems. In this context, this work presents a novel control strategy applied in the dc-ac converter used in the primary side of a WPT system. The performance of a class-DE resonant inverter is investigated considering that such topology presents inherent soft-switching characteristics, thus implying reduced switching losses. The controller relies on an autoregressive with exogenous output (ARX) model based on an adaptive linear neuron (ADALINE) network, which allows for determining the turn-on time of the active switches accurately while providing the system with the ability to adapt to distinct alignment conditions. The performance of the proposed controller is compared with that of a linear controller, which does not prove to be an effective solution if misalignment occurs.

“…The analysis results show that the primary and secondary current total harmonic distortion is only related to the inductance of the secondary coil, the load, and the coupling factor in a series-series WPT system. A prototype has been built and tested experimentally to validate the proposal [118]. The inverter stage and the rectifier stage are modeled as square voltage sources v 1 and v 0 .…”

“…In order to validate those equations, a WPT prototype system has been designed [118], the schematic of the experimental setup is shown in Figure B.5. The inverter stage chosen for the WPT system is the ZVS Class D amplifier [52] and [90], which comprises two main components: namely a half bridge switching converter (S 1 and S 2 ), and a ZVS tank circuit (L ZV S and C ZV S ).…”

Mazaheri and so on. I am grateful to have shared this important phase of my life with you in Madrid. To all the laughters, beers, dinners, Wednesday movies and seminars.Finally, I would like to dedicate this thesis to my parents, Tongxi Shi and Xianhua Wei. Your never-ending love and unconditional support have always given me one more reason for being a better version of myself. In every step forward of my life, I have owed them a great debt of thanks that cannot be expressed in any words. Also, I would like to thank my two elder sisters for taking care of our parents while I am staying far away from home, which helps me stay focused on this thesis.
