Journal on Electrical Engineering 2230 – 7176 6 3 21 29 Boost Converter, Buck-Boost Converter, PI Controller, Fuzzy Logic Control In this paper, an ac/dc converter is presented that can boost very low ac voltages to a higher dc voltage. The converter is based on a new hybrid form of boost converter and a buck boost converter and it is suitable for power harvesting applications too. The measured prototype can supply 3.3V by converting an input voltage of 400mV delivered by an electromagnetic microgenerator. Detailed analysis of converter is carried out and based on that control schemes are proposed to operate the converter. January - March 2013 Copyright © 2013 i-manager publications.
