【摘要】 针对双负载无线充电系统中存在的交叉耦合问题,利用电路理论对系统进行建模,从电流向量、负载端电压及系统效率等方面,量化分析了交叉耦合现象,得出使系统谐振点发生偏移的结论,提出利用传输因式的方法确定补偿网络,解决这一问题,并验证其可行性,同时,在解决交叉耦合的条件下,通过增加负载端个数来增加系统效率,整个系统效率提升了8.17%.更多还原

【Abstract】 Cross-coupling effect of multi-receivers wireless power transfer system makes the system resonance point shift,circuit theory is used to establish model to quantify the effect from the factors such as coil current vector,load voltage and system efficiency. The transmission factor can be used to determine the compensation network to solve this problem,and its feasibility is verified. At the same time,under the condition of solving cross-coupling,the system efficiency is improved by increasing the number of load terminals,and the overall system efficiency is increased by 8.17%.更多还原
