提高感应电能传输效率的研究

非接触式感应电能传输系统（ICPT）是一种新型的电能传输技术,通过感应电磁耦合向负载提供电能。ICPT的关键部件是松耦合变压器（也叫可分离变压器）它的耦合系数较低,制约着传输效率。本文对非接触感应电能传输系统进行了系统的介绍,并且分析了磁芯材料、工作频率、气隙大小等关键参数对传输效率的影响,着重讨论了可分离变压器的初次级绕组的补偿问题,并且给出了补偿电路的设计方案。

Research and implementation of high-frequency inverter circuits

The contact less inductive coupled power transfer system is one of the newest power transfer technology , which transmit energy to load by electromagnetic coupling. The key components of ICPT are the coupled transformer （also named detachable transformer）. It has lower coupling coefficient so that it restricts the transmission efficiency. In this paper, it introduces the system of the ICPT, and analyses the influence of the transfer efficiency which impacting by the core material, working frequency, air-gap and so on. And it focuses on the compensation issue of the coupled transformer, and giving the designing program of the compensation circuit.
