Abstract: Different from widely used low-voltage (LV) input to LV output inductive coupled power transfer (ICPT) systems with low power level, the LV input high power ICPT systems with HV output suffer from the following key challenges: (1) high conduction losses in the primary side, especially at the transmitter coil; and (2) high-voltage boost ratio, such as 28V input and 280V output, results in difficulties in designing the compensation parameters and loosely coupled transformer. To solve these issues, a novel ICPT topology is proposed in this paper by incorporating interleaved boost inverter and voltage doubler rectifier. Thus, the distinctive features of the proposed IPT system are the reduced designing difficulties for the compensation parameters and loosely coupled transformer due to the inherent high boost ratio and the decreased conduction loss of primary transmitter coil. To validate the features of the proposed solution, a prototype with 28V input, 280V/5A output, 50mm air gap, 300×300mm coil size is built and tested. The experimental results show that the efficiency is maintained above 94% under the load current of 1~5A and the peak efficiency is high as 95.61%.
