摘要
交流感应电能传输系统根据法拉第电磁感应定律,通过空气介质实现了电能的无线传输,克服了以导线为媒介直接传输电能的缺陷,首先推导了一次侧谐振频率与二次侧负载电阻和一、二次侧感应耦合系数之间的关系模型,并对在回路无补偿、并联补偿情况下进行仿真,其次对一次侧电流和二次侧电压的幅频特性和相频特性进行了分析,确定影响系统传输效率的因素,验证了在一次侧补偿电路和二次侧补偿电路同时发生谐振时,系统传输效率最高。同时设计了交流感应电能传输系统传输变换器并应用Multisim 10软件对控制器进行了仿真,确定了这一方法的正确性。
According to Faraday law of electromagnetic induction, air power transmission was used by ac induction electric power transmission system. The defects of the transmission of electrical energy application wires were overcome. Relation model was derived on resonant frequency and the load resistance and coupling coefficient. Amplitude frequency characteristics and phase frequency characteristics were analyzed on the primary side currents and secondary side voltage. The secondary side circuit was without paral el compensation. The efficiency was frequently influenced. And the system transmission efficiency was highest, when resonance occurs the primary side and secondary side compensation circuit at the same time. Software Multisim 10 simulation circuit was applied. Final y, the design of the hardware portion of a smal power-power transmission was correct.
