Research of loosely coupled transformer transfer characteristic in contactless power transfer system

本文是对基于非接触感应电能传输技术的全桥谐振变换器的传输特性进行的研究。松耦合变压器是非接触电能传输系统中的关键部件,本文首先分析了松耦合变压器与传统紧耦合变压器的区别进而提出原副边补偿问题,其次计算出串串补偿和串并补偿电容的选取,再次计算当系统工作在谐振状态时电压的放大倍数并得出负载特性,最后通过PSpice软件搭建电路并仿真,证明分析和结论的正确性。

This article is mainly discuss the full-bridge resonant converter transmission characteristics based on non--contact inductive power transfer technology. Loosely coupled transformer is a critical component in the non-contact power transmission system,This paper analyzes the distinction between loosely coupled transformer and the traditional tight coupling transformer, Second, calculate the value of compensation capacitance, thirdly, summary voltage gain when the system operates in resonant state and draw load characteristics,finally use PSpice simulation software to build circuits, prove the correctness of analysis and conclusions.
