在最大链路效率IPT设计中，需要固定的交流负荷值。为此，必须使整流器的输入阻抗与最优交流负载相匹配。本文提出了一种用于6.78 MHz IPT系统的带电阻压缩网络的电流驱动D类整流器，其反射交流负载在较宽的直流输出负载范围内具有最小的变化。实验结果表明，在保持高效率的情况下，输出直流负载在10Ω~80Ω范围内的电阻偏差为31%。记录的接收端效率为96.5%~88.2%。在电阻偏差中实现的压缩可能潜在地将寄主感应链路的效率保持在95%以上。
In maximal link efficiency IPT design, a fixed AC load value is required. For this reason, matching the value of the input impedance of the rectifier to the optimal AC load is necessary. This paper presents a current driven Class D rectifier with a resistance compression network for 6.78MHz IPT systems, in which the reflected AC load has a minimal variation for a wide range of DC output loads. Experimental results showed a resistance deviation of 31% for an output DC load varying from 10Ω to 80Ω while maintaining high efficiency. Recorded receiving end efficiency range from 96.5% to 88.2%. The achieved compression in resistance deviation could potentially maintain the efficiency of the hosting inductive link above 95%.
