摘要：
This paper extensively investigates the analysis, design, and practical implementation of a class E resonant inverter with zero voltage switching (ZVS) capabilities, specifically tailored for wireless charging applications. The equivalent circuit of the Class E inverter utilized in wireless power transfer is thoroughly examined to derive the requisite formulas. The modes of operation were thoroughly analyzed by studying the corresponding waveforms. Based on the derived formulas, the circuit parameters were calculated. To validate the proposed design, a prototype of the wireless power transfer system was developed. Both simulation results and experimental findings confirmed the successful transfer of wireless power, achieving the desired output power. Additionally, it was observed that the power switch can operate under ZVS condition for horizontal misalignments within the range of 0-18 mm and a vertical distance between the coupled coils of 5 mm.
