中文摘要:
      针对三线圈无线电能传输系统中继线圈的位置对系统的输出功率和传输效率等传输特性的影响问题展开研究,设计一种采用DC-DC转换电路的传输策略,使得整个系统能在中继线圈的摆放位置不发生改变的情况下,通过调整负载的等效阻抗,将传输效率维持在一个较高的水平. 实验结果表明,该传输策略不仅适用于中继线圈固定、负载阻值改变的情况,在负载保持不变而中继线圈位置产生变化时依旧能保持较高的传输效率.
英文摘要:
      This work analyzed the influence of the position of relay coil on the output power and transmission efficiency in the three-coil wireless power transmission system. A transmission strategy using a DC-DC conversion circuit was designed to maintain the transmission efficiency at a high level by adjusting equivalent impedance of load without changing the placement of the relay coil. The experiments show that the proposed transmission strategy is not only suitable for the situation where the relay coil is fixed and load resistance is changed,but also can maintain high transmission efficiency when the load remains the same but the position of the relay coil changes.
