感应耦合电能传输系统中同步整流的分析

对于感应耦合电能传输系统，整流电路通常使用整流二极管，其损耗尤为突出，使得系统整体效率低下。同步整流技术可提高系统效率。而传统的同步整流方式，无法应用在感应电能传输系统中。文章系统分析了这些弊端，提出了一种全新的同步整流电路控制驱动技术。最后，提出一种可行的系统方案，并用Cadence SPB 16．3中的Pspice工具进行了仿真。

An analysis of Synchronous Rectifier in Inductive Coupled Power Transfer System

For the Inductive Coupled Power Transfer System （ICPTS）, the rectifier diode is commonly used in a rectifier circuit. Rectifier loss is particularly prominent, degrading the efficiency of the system. Application of synchronous rectification technique could increase the system efficiency. But the traditional synchronous rectification system, could not be used in the ICPTS. This paper thoroughly analyzes the traditional synchronous rectification system. Finally, we propose a novel control technology for synchronous rectifier circuits, and demonstrates a feasible system solution, which is simulated by Pspice.
