This paper presents two novel extended non-breakdown rectifier topologies, which practically solve the rectifier?s early breakdown for the power-optimized waveform (POW) based wireless power transfer (WPT) systems. By utilizing two depletion-mode MOSFETs with different doping types, the proposed rectifier?s breakdown voltage extends while maintaining its low forward threshold voltage. It would keep high power conversion efficiency (PCE) even with high peak-to-average power ratio (PAPR) of transmitted signal. Theory analysis shows that the proposed rectifier would achieve an extended breakdown voltage with double value compared to prior work with reverse leakage current shrinkage while preserve its original low threshold voltage. The two proposed non-breakdown rectifier topologies would bring insight for the practical high efficiency POW based WPT systems. |
