摘要
无线充电系统需要满足与负载无关的恒定输出电流和零相位角充电过程,来实现高传输效率。现有的恒流充电型系统存在输出电流受松耦合变压器参数的限制、接收侧体积大、开发成本高等问题。提出了一种LCC/N补偿拓扑无线充电系统及其相应的参数调整方法,在ZPA运行下实现恒定电流充电。由于接收侧不需要补偿元件,因此保证了WPT系统实现恒定电流充电模式的前提下,还满足了接收侧的紧凑性和轻便性,节省了生产成本。
The wireless power system must satisfy the load-independent constant current and zero-phase angle charging process to achieve high transmission efficiency.The existing constant current charging system suffer from issues such as limited output current due to the parameters of loose coupling transformer,large size on the receiving side,and high development cost.In this paper,we propose an LCC/N compensation topological for the wireless power system,along with a corresponding parameter adjustment method in order to achieve constant current charging under ZPA operation.Since the receiving side does not require compensation elements,the WPT system ensures constant current charging while maintaining the compactness and portability of the receiving side,thereby reducing production cost.
