Study of Double-Sided LCC Compensation Wireless Power Transfer Based on Zero Voltage Switching

摘要

The working principle and characteristics of double-sided LCC resonant network in magnetically coupled resonant wireless power transfer (WPT) are analyzed. The circuit parameters are optimized by combining the output current of the original side inverter circuit, and the zero voltage switching (ZVS) of the inverter circuit is realized. This paper presents a controlled rectification power control mode and introduces the working flow. This mode realizes the ZVS of rectification circuit while adjusting the output power. The rationality and effectiveness of the proposed parameter optimization and control method are verified by simulation.
