Abstract

A rectifier for wireless power transfer is disclosed. The rectifier comprises an electromagnetic signal receiving element operable to be driven with an electromagnetic signal oscillating at a first frequency; a first tank circuit comprising a first inductor and a first capacitance in series; a second tank circuit in parallel with the electromagnetic signal receiving element, the second tank circuit comprising a second inductor and a second capacitance in series; a third capacitance in parallel with the electromagnetic signal receiving element; and a rectifying element in parallel with the first capacitance, wherein: the first inductor is in series with the electromagnetic signal receiving element between the electromagnetic signal receiving element and the second tank circuit, the first capacitance is between the second tank circuit and the third capacitance, and the second inductor and the second capacitance are selected such that the resonant frequency of the second tank circuit is an integer multiple, greater than one, of the first frequency.
