Realization of energy harvesting system using a frequency generator

This paper presents the hardware implementation of a frequency converter and AC/DC step up converter for realising the low voltage energy harvesting. In the simulation part, the input of the AC/DC converter is from an electromagnetic micro generator which converts vibration into electrical energy. The electromagnetic micro generator is being modelled and simulated. But in the hardware implementation, a frequency generator has been designed to generate the output of micro generator. The AC/DC converter is controlled by ARM7 microcontroller. A closed loop control is incorporated.
