Iterative Non-breakdown Rectifier Topology for Via-Tissue Multi-sine Wireless Power Transmission

This paper presents a novel iterative non-breakdown rectifier topology which would practically solve the rectifier's early breakdown problem in multi-sine wireless power transmission (WPT) for biomedical application. The proposed rectifier holds an iterative topology which can extend the reverse breakdown voltage limitlessly with its forward threshold voltage remains. It keeps high conversion efficiency even with the high peak voltage input in multi-sine WPT application. Measured I-V curve shows that the proposed rectifier would achieve an extended breakdown voltage from -7.5 V to -52V with a low reverse leakage current while keep its original forward threshold voltage. The proposed rectifier topology brings insight for the practical high efficiency multi-sine WPT system design.
