摘　　要：电动汽车无线充电输出功率波动控制性能过差会降低电动汽车无线充电传输效率和充电功率,为了提高输出功率稳定性,提出电动汽车无线充电输出功率波动控制方法。分析电动汽车无线充电装置各部位器件在一次充电过程中能够产生的等效电路参数,建立电动汽车无线充电模型。分析导致模型输出功率波动的原因,获取能够实时展现功率输出特性及功率波动情况的等效电路输出功率表达式。参照动态解耦工作原理使电动汽车无线充电模型从耦合状态转变为解耦暂态,根据输出功率表达式提供的峰值输出功率,调节等效电路负载电流、负载电压及负载电阻,实现电动汽车无线充电输出功率波动控制。仿真结果表明,所提方法控制性能较好。If the control performance of the fluctuation in output power of wireless charging is not ideal,the transmission efficiency and wireless charging power for electric vehicles will decrease.In order to improve the stability of output power,a method for controlling the fluctuation in output power of wireless charging for electric vehicles was put forward.Firstly,we analyzed the equivalent circuit parameters generated from the component in the wireless charging device of electric vehicles during a charging process,and then built a wireless charging model for electric vehicles.Moreover,we analyzed the reasons for the fluctuation in output power,thus obtaining an expression of the output power of an equivalent circuit that could display the characteristics of power output and fluctuations in real-time.According to the dynamic decoupling principle,we changed the wireless charging model from a coupled state to a decoupled transient state.Based on the peak output power provided by the expression of output power,we adjusted the load current,load voltage,and load resistance of the equivalent circuit.Finally,we achieved the control of fluctuation in wireless charging output power.Simulation results show that the proposed method has better control performance.
