N2 - In this article, a simultaneous wireless power and data transfer (SWPDT) system with two duty cycles Class-E inverter is proposed. By solving the time-domain analytical expressions, the proposed inverter outputs amplitude varies with the different duty cycles. Therefore, it can facilitate simultaneous wireless power data transfer by the amplitude-shift keying (ASK) without any auxiliary circuit. Moreover, zero-voltage switching (ZVS) operation can be achieved for both two modes. A 1 MHz, 7W experimental prototype is built to verify the proposed method. Additionally, data are transferred successfully at the rate of 100 kbps and the two duty cycles are 0.35 and 0.7 respectively. The maximum measured circuit efficiency achieves 80.2%.
