摘要:
通过原理分析,提出了海水中感应耦合无线电能传输( ICWPT) 系统的电路模型,其中考虑了海水的涡流效应,建立了匹配条件下传输效率的表达式。作为对比,基于单个超声换能器的电路模型,建立了包含两个超声换能器的超声耦合无线电能传输( UCWPT) 系统电路模型,分析了匹配条件下的传输效率。分别以矩形耦合线圈作为电磁耦合装置,以压电复合材料换能器作为电声和声电转换装置,搭建了在海水槽中 ICWPT 和 UCWPT 系统实验平台。分别从传输效率与工作频率的关系、传输效率与耦合距离的关系进行了比较,并对传输功率进行了讨论。研究发现,ICWPT 的传输效率与频率的关系曲线比 UCWPT 的效率与频率关系曲线更加平坦。较远距离时,UCWPT 的传输效率高于 ICWPT 的传输效率。关键词:
Abstract:
Through analysis of the principle,the circuit model of inductive coupling wireless power trans-mission( ICWPT) system in seawater was proposed,which considered the eddy current effect of seawater.The transmission efficiency under matching condition was established. As a contrast,based on the circuitmodel of a single ultrasonic transducer,a circuit model of ultrasonic coupling wireless power transmission( UCWPT) system with two ultrasonic transducers was established,and its transmission efficiency undermatching conditions was analyzed. The ICWPT and UCWPT system experimental platforms were construc-ted by using the rectangular coupling coil as the electromagnetic energy coupling devices and the piezoe-lectric ( PZT) composite transducer as the electro-acoustic and acoustic-electro conversion devices. Rela-tionship between transmission efficiency and operating frequency,transmission efficiency and couplingdistance was compared,respectively,and the transmission power was also discussed. It is found that thetransmission efficiency vs frequency curve of the ICWPT system are flatter than that of the UCWPT sys-tem. At longer distances,the transmission efficiency for UCWPT system is higher than that of the ICWPT system.
