A loosely coupled rotary transformer with an improved core structure
Source abstract
Abstract
The loosely coupled transformer has high leakage inductance and a low coupling coefficient because of the large air gap, resulting in low efficiency. To address the issues, a loosely coupled rotary transformer with an improved pot core structure is proposed by increasing the number of winding turns and decreasing the size of the central limb. First, the equivalent magnetic circuit model of the loosely coupled rotary transformer is built to analyze the relationship between different parameters of the rotary transformer. Second, the finite element analysis software is used to analyze the 2D and 3D models of the pot core rotary transformer and validate the correctness of the proposed structure. Finally, pot core rotary transformer prototypes and a contactless energy transfer system experimental platform are constructed to compare the performance of the traditional and improved rotary transformers, and the effectiveness of the proposed scheme is further verified by experimental results.
