CONVERTER OF UHF-RANGE ELECTROMAGNETIC WAVE ENERGY INTO CONTINUOUS VOLTAGE Russian patent published in 2012 - IPC H02M7/10 

FIELD: electrical engeneering.

SUBSTANCE: remote transmission and conversion of ultra high frequency electromagnetic energy into direct electric current and can be applied for low-power rectifier. Converter of UHF-range electromagnetic wave energy into continuous voltage contains antenna and rectifier, having N stages of voltage multiplication and containing 2N or 4N valve elements. Valve elements of the rectifier are diodes with PWL volt-ammeter curve with point of inflection at 0 V expressed by I=S₁*U with U>0 and I=S₂*U with U≤0, where S₁ and S₂ - constant coefficients. Coefficients ratio S₁/S₂ is no less than 100 with S₁ coefficient being 10^-4 Ohm^-1 to 10^-2 Ohm^-1.

EFFECT: increased effectiveness of rectifier conversion of varying voltage into constant by 3…10 times with input signal power less than 20μW and the possibility of coordination of rectifier with antenna without using additional transformer in output resistance range of antenna from 20 to 1000 Ohm.
