摘要: This paper presents a novel self-starting low-voltage step-up DC-DC converter for energy harvesting from ultra-low-power and sources. The proposed structure consists of two stages: the first stage is an autonomous oscillator, which provides self-start-up capability with low-input voltages, second controllable reverse conventional buck-boost converter. simulated using ORCAD 16.5 also its laboratory prototype fabricated. Simulation results experimental tests confirm that this able to harvest ultra-low powers as small 40µW microbial fuel cell, while feeding 510 kΩ load DC voltage over 2.7V.
