N2 - In order to cope with the different voltage and power requirements in the capacitive power transfer (CPT) system, an effective pulse frequency modulation (PFM) method for the inductor-capacitor (LC)-LC compensated CPT system is proposed in this paper. The LC-LC compensated CPT can inherently realize constant output voltage characteristics, independent of load and coupling capacitance. In addition, the PFM control can realize flexible and effective output voltage regulation while enabling zero voltage switching (ZVS), thus reducing switching losses and improving the system efficiency. Detailed computational evaluation and theoretical analysis are conducted to assess the viability of the proposed PFM-CPT system.
