Abstract:V disertaciji je predstavljen razvoj merilnih sistemov, ki se lahko uporabljajo kot pomoč pri razvoju sistemov za brezžični prenos energije. Ker so sistemi za brezžični prenos energije kompleksnejši kakor klasični sistemi, ki energijo prenašajo preko žice, je tudi njihovo oteženo. Najbolj pomembna parametra pri brezžičnem prenosu energije, s pomočjo induktivne metode sta koeficient sklopljenosti med oddajnim in sprejemnin navitjem in gostota magnetnega polja, preko katerega se energija prenaša. Koeficient sklopljenosti vpliva na izkoristek sistema. Zaradi zračne reže med oddajnim in sprejemnim navitjem je koeficient sklopljenosti majhen. V primeru neporavnanosti med navitji, koeficient sklopljenosti še dodatno upade. Za pomoč pri iterativnem načrtovanju in integraciji navitij smo razvili merilni sistem, ki omogoča meritev koeficienta sklopljenosti v 3D prostoru. Gostota magnetnega polja zraven vpliva na koeficient sklopljenosti, pomembna za določitvi izsevanega magnetnega polja v prostor med samim procesom razvoja in integracije. Zato je bil razvit tudi merilni sistem, ki omogoča meritev gostote magnetnega polja oddajnega navitja, ki se napaja z razsmernikom tipa D.

Title:Measurement and validation of electromagnetic coupling and magnetic flux density of the coils in wireless power transfer using class D inverter
Abstract:The thesis presents the development of the measurement equipment, that can be used during the design of the wireless power transfer systems. The wireless power transfer systems are more complex compared to the wired, plug-in charging. This complexity makes the development of the wireless power transfer systems more difficult. The most important parameters of the inductive wireless power transfer systems are the coupling coefficient between the transmitter and the receiver coil, and the magnetic flux density that transfers the power from primary to secondary side. The coupling coefficient impacts on the system efficiency. Due to the large air gap between the transmitter and the receiver coil, the coupling coefficient is low. In the case of the misalignment between the coils, the coupling coefficient additionally decreases. To help with the iterative wireless power transfer coil design process, the measurement system was developed. The measurement system measures the coupling coefficient between the transmitter and the receiver coil in 3D space. The magnetic flux density impacts on the coupling coefficient and on radiate magnetic field during the coil integration process. The developed magnetic field measurement system enables measurement of the magnetic filed, generated by the transmitter coil, excited by the class D inverter.
Keywords:inductive power transfer, class D inverter, magnetic flux density, magnetometer, coupling coefficient
