摘要：
This paper presents an intermodulation harvesting rectifier design for multi-sine wireless power transfer (WPT). It provides a practical solution to reduce the output ripple in multi-sine WPT as well as a substantial efficiency improvement. The mechanism analysis of multi-sine WPT is presented and the Intermodulation harvesting rectifier circuit is accordingly designed to improve power transmission performance. Measured results show that the multi-sine WPT with the proposed rectifier could achieve both a 10% efficiency improvement from traditional WPT systems and a stable DC output with less ripple. It provides a good reference when designing a stable high efficiency WPT system.
