用于混合储能系统供电的无线电能传输技术效率优化策略研究
|
摘要
混合储能系统具有高功率密度和高能量密度的双重优势,但是很少有研究考虑混合储能系统的无线充电策略设计,本文考虑无线电能传输技术特性,优化了混合储能系统的功率分配策略。首先,给出无线电能传输系统对混合储能系统充电的电路,补偿拓扑采用原边电感/电容/电容方式-副边串联电容方式。这种补偿拓扑具有恒定的二次电压输出,如果适当调整混合储能系统的功率,即可改变无线电能传输系统的等效负载,使其达到最优值,从而维持系统最优效率。其次,优化设计了混合储能系统的功率分配方式,提出混合储能系统的无线充电策略。这种策略既能满足系统能量输出的要求,又能保证系统高效工作。最后,通过实验验证了上述方法的可行性。
Hybrid energy storage system(HESS) has dual advantages of high power density and high energy density, but it is rarely discussed for wireless power transfer(WPT) system. Considering the characteristics of WPT system, this paper optimized the power allocation strategy of HESS. First,the circuit of the WPT system charging for HESS is proposed, the circuit adopts a primary-side inductor/capacitor/capacitor compensation and secondary-side series compensation topology. The compensation topology has a constant voltage output of the secondary side, the equivalent load of the coupling coils can be controlled to the optimal value if the input power of HESS is adjusted properly,thus the system optimal efficiency is maintained. At the same time, the wireless charging strategy of HESS is designed according to the power allocation mode of HESS. This control strategy can not only meet the requirements of the system energy output, but also maintain high efficiency of the system.Finally, the feasibility of the control method is verified by experiments.
