This paper describes the interface electronics for a vibration based Electromagnetic (EM) energy harvester, which works on the mechanical frequency-up-conversion principle. The interface electronics is used to step up and rectify the harvested AC signal of the energy harvester through a two-stage charge-pump circuit. Output voltage of 4.5 V with 2.5% ripple has been demonstrated at a load current of 5 μA. The maximum power efficiency is 35% with an output voltage and current range of 2-2.5 V and 15-20 μA respectively. Furthermore, a synchronous rectifier was powered by the energy harvester to verify usage under active loading conditions.

Sari, Ibrahim; Balkan, Raif Tuna; Külah, Haluk (2008-06-25)
In this paper an electromagnetic vibration based micro power generator is presented. The proposed generator is composed of parylene cantilevers on which planar coils are fabricated. The system uses external vibrations to generate power by virtue of the relative motion between the cantilevers and a magnet. The parameters of the micro generator have been optimized for maximum output and it has been fabricated in micro scale. Initials tests show that 8.75 mV could be obtained from the proposed generator at a v...

Zorlu, Ozge; Topal, Emre Tan; Külah, Haluk (2009-10-28)
This paper presents a new mechanical frequency up-conversion (FUC) mechanism for harvesting energy from external low frequency vibrations. The structure consists of a magnet placed on a support, a polystyrene cantilever carrying a pick-up coil, and a mechanical barrier which converts low frequency vibrations to a higher frequency, hence increasing the efficiency of the system. The tested structure proved to give 20.3 mV and 68.7 mu W RMS power output by up-converting 10 Hertz external vibration to 643 Hertz...

Külah, Haluk (2004-01-01)
This paper presents an electromagnetic (EM) vibrationto-electrical power generator which can efficiently scavenge energy from low-frequency external vibrations. The reported generator up-converts low-frequency environmental vibrations to a much higher frequency through a novel electro-mechanical frequency up-converter using a magnet, and hence provides efficient energy conversion even at low frequencies. Power is generated by means of electromagnetic induction using a magnet and coils on top of resonating c...

Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2014-11-05)
This paper presents an interface circuit for efficient rectification of voltages from electromagnetic (EM) energy harvesters operating with very low vibration frequencies. The interface utilizes a dual-rail AC/DC doubler which benefits from the full cycle of the input AC voltage, and minimizes the forward bias voltage drop with an active diode structure. The active diodes are powered through an AC/DC quadrupler with diode connected (passive) transistors. The interface system has been validated to drive 22 m...
