摘　　要：首先介绍了无线能量传输系统的基本构成和初次级电容补偿模型,然后建立以松耦合变压器为基础的无线电能传输系统,对不同初次级电容补偿模型进行试验研究。结果表明:初级串联补偿可以显著降低电源所需供应的电压,初级并联补偿可以有效降低初级绕组的电流。次级补偿也可降低输入电压和初级绕组的发射电流,与初级补偿相比,电压下降幅度小得多。在初次级均补偿情况下,输入电压和初级绕组电流均下降,功率因数都有提高。在串并补偿情况下输入电压最小,功率因数最高。The basic constitutions of a Wireless Power Transmission（WPT）system and primary and secondary compensated topologies are introduced.Then,based on a loosely coupling transformer,the WPT system are designed.The results show that the primary compensated in series can reduce the voltage of power supply evidently,the primary comensated in parallel can reduce the current of the primary;the secondary compensated may also reduce the input voltage and primary winding＇s emission current,compares with the primary compensated,the voltage decline rate is much smaller;both the primary and secondary compensated,the input voltage and the primary current drop,the power factor is increased.But in the situation of SP comensated model,the input voltage is the smallest and the power factor is the highest.
