摘要

For 13.56 MHz wireless power transfer (WPT) systems, a multiple-input single-output (MISO) AC/DC converter is proposed in this paper. To supply DC voltage from small vibration inputs such as 1 V, 12 times gain is realized by the proposed converter. Unlike conventional converters, the proposed MISO converter has the hybrid C ockcroft- W alton/Dicks on (HCWD) topology. The MISO HCWD topology enables the proposed converter to achieve high gain with low voltage stress. To clarify the effectiveness of the proposed converter, theoretical analysis and computer simulations are performed by using the simulation program with integrated circuit emphasis (SPICE) simulator. The result of the computer simulations showed that the proposed converter can provide a DC output from 1 V at 13.56 MHz input, where the power efficiency reaches 67 with an output power of 10 mW. Furthermore, the comparison between the proposed converter and the conventional converters, such as single-input single-output (SISO) Cockcroft-Walton converter, SISO Dickson converter, and SISO HCWD converter, reveals that the proposed converter can achieve excellent performance in terms of output voltage, power efficiency, voltage gain, and ripple factor.
