摘要
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。为了提高传输效率,必须给变压器初级线圈提供高频交流电源,本文介绍了一种带可分离变压器的全桥高频逆变电路及其主控电路,分析了它们的工作原理以及它的等效电路模型,在仿真软件Multisim中对逆变电路进行了仿真,并且搭建了主控和逆变电路,进行了逆变实验,在主控电路的控制下,逆变电路输出高频交流信号,频率从0Hz—100KHz实验结果与仿真结果一致。
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 is the coupled transformer（ also named detachable transformer）. It has lower coupling coefficient so that it restricts the transmission efficiency. In this paper,a kind of the full-bridge high-frequency inverter circuits With detachable transformer is introduced, it analysis the working principles and the equivalent circuit model of the circuits, simulate in the Multisim software,build the inverter and control circuits and do the experiment,the outputs of the inverter circuits is high frequency AC signal. The experimental results is coincident with the simulation.
