Abstract: 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%.
