Abstract [en]

This report presents the analysis of a novel capacitance-based multilevel bias flip rectifier used to increase the output power from a piezoelectric vibration energy harvesting system. The ideal voltage flipping efficiency is calculated based on the number of levels used followed by an analysis of the power losses caused by the bottom-plate parasitic capacitance of the flying capacitor used to distribute the charge between the levels. Then the time to complete the bias flip is examined and the difference between using either a diode or energy investment is investigated. This analysis is intended to be used for aiding in the design of such a system.
