N2 - The two-stage wireless charging system is used in various wireless charging application because its power factor correction (PFC) rectifier and the inverter are decoupled from each other and the control is more convenient, but the large number of power switches and bulky electrolytic capacitors results in low power density of the system, so a number of single-stage solutions were put forward. In this paper, a novel single-stage wireless charging system without bulky DC capacitors is proposed to replace the two-stage one, which is composed of only six switches and two diodes. Moreover, a phase-shifting (PS) modulation scheme is proposed based on this single-stage topology, which can realize power regulation, PFC, and soft switching simultaneously. Finally, a simulation prototype is built to verify its effectiveness.
