Abstract

This analysis shows that, the coordinated Switch Harvesting on Inductor topology is higher in output power at small vibrations at 1Hz. The recital of the topology at a frequency of 1Hz and output power levels around 10μW was found to positive and negative with the peak detection control circuit performance. The sample showed to increase the output power by a factor of two, compared to the standard full bridge rectifier, but when accounting for the control circuit power consumption of 13.2μW the gained output power was lost. The control circuit showed to be more of a limiting factor than expected and a set of requirements for a new control circuit was made. At higher energy levels the sample is expected to increase the output energy by up to 10 times and to extend the range of feasible low frequency energy harvesting sources and applications.
