“…2 3.3. Modelling of resistors 𝑅 𝑝 and 𝑅 𝑠 Due to the working frequency of the WPT system between 79 and 90 kHz, it is necessary to use a Litz wire to reduce losses, both skin effect 𝑃 𝑠𝑘𝑖𝑛 and proximity 𝑃 𝑝𝑟𝑜𝑥 (Acero, Carretero, Lope, Alonso, & Burdío, 2016;Guillod, Huber, Krismer, & Kolar, 2017;Stadler, 2013;Tourkhani & Viarouge, 2001). In order to consider these losses, the resistances of the conductors that allow their modelling 𝑅 𝑠𝑘𝑖𝑛 and 𝑅 𝑝𝑟𝑜𝑥 , respectively, are calculated, where 𝑅 is the total resistivity of the Litz coil:…”
