Abstract：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.
