摘要

This paper designs a 3kW magnetic resonance wireless charging system for electric vehicles (EVs), and an explicit solution is derived. The maximum power transmission efficiency (PTE) is above 90% in this system. By the way of adjusting the duty ratio, this system adapts the dynamic change of the battery load and balances current of the transmitting coil and receiving coil. At the same time, the charging power and PTE are also greatly increased.
