Abstract
Increasing production of electric vehicles (EVs) and the challenge of charging these types of vehicles have been one of the most important research topics in the current century. Due to the low-battery energy density of EVs (compared to fuel) as well as the long time required to charge EVs, wireless power transfer (WPT) technology is an interesting topic researched in recent years. The WPT system in EVs can be studied in both static and dynamic scenarios. In this study, symmetrical circular couplers are first presented as system magnetic couplers and their magnetic calculations are analyzed using finite element method. Then, a new approach is proposed to design the power electronic circuits of the WPT, including a double-sided LCC compensator, and providing an approximation for calculating the ratio of output to input voltage. This method shows how to select the appropriate values of the passive elements for high system efficiency that can meet the output power and voltage. Firstly, the efficacy of the proposed approach is confirmed by experimental and simulation results. Then, using the input control of inverter MOSFETs through pulse width modulation method and proportional integral controller, the output voltage of the system is kept constant while increasing or decreasing the input voltage.
