Using piezoelectric elements to harvest energy from ambient vibrations has been of great interest over the past few years. This paper presents a two-stage adaptive boost converter with low-voltage starter for low voltage piezoelectric energy harvester. The adaptive technique can deal with a range of input voltages from the excited piezoelectric generator for required output voltages. The parameters of the converter including inductance, switching frequency, duty cycles and the input/output voltage are studied for better conversion efficiencies. The simulation results show that a two-stage adaptive boost converter can achieve a high efficiency of 92.3% for low voltage piezoelectric harvester to charge an energy storage device with higher voltage.
