Enhanced DC-DC converter, method for operating the DC-DC converter, environmental energy-harvesting system comprising the DC-DC converter, and apparatus comprising the energy-harvesting system

摘要

A DC-DC converter independently supplies electrical loads. For each load, an output load signal is compared to a reference to generate a result indicating a need to supply the respective electrical load. A first detection is made as to whether a first electrical load needs to be supplied and a second detection is made as to whether any remaining electrical loads need to be supplied. The first electrical load is supplied if the first detection is positive and the second detection is negative.
