Abstract

Wireless power transfer (WPT) is a novel and valuable charging method because of its convenience. In order to further develop its superiority, the supercapacitor (SC) is used as the energy storage device in WPT which could significantly improve the charging speed. In this paper, a two-side control method is proposed to ensure the charging current stable. An inverter with disturbance observer based control (DOBC) controller is implemented on primary side to maintain constant output voltage for the variable primary side current. Then a Buck converter with proportional integral (PI) controller is implemented on the secondary side to maintain constant charging current for the variable load. Compared with conventional charging method, the charging time has been reduced by 40% via the method proposed in this paper.
超级电容器无线电力传输系统快速充电方法研究
无线充电技术以其便捷的充电方式成为一种新颖而有价值的充电方式。为了进一步发挥其优势,在WPT中采用超级电容器作为储能器件,可以显著提高充电速度。为了保证充电电流的稳定,本文提出了一种双向控制方法。在一次侧采用基于扰动观测器控制(DOBC)控制器的逆变器,在一次侧电流变化时保持输出电压恒定。然后在二次侧采用带比例积分(PI)控制器的Buck变换器,以保持可变负载的恒定充电电流。与传统充电方式相比,充电时间缩短了40%。
