Inductive power transfer (IPT) which transfers power from source to load through electromagnetic coupling, is being considered as a promising technology for charging of electric vehicles (EVs). IPT system is a double tuned circuit, i.e. two capacitors are added to form two resonant tanks with primary and secondary coil inductances. The secondary compensation circuit is added to improve the power transfer capability of the system and primary capacitor is so chosen to operate the inverter output at unity power factor. However, during practical implementation, switching frequency is deviated from resonant frequency to accommodate soft-switching in inverter switches. This paper deals with the impact of deviation from an ideal resonant frequency on efficiency and power transfer capability of the IPT system. In this paper, a series-series compensated IPT system has been considered for the analysis using PLECS simulation. © 2017 IEEE.
