Power delivery mechanisms for asynchronous loads in energy harvesting systems
PhD ThesisFor systems depending on methods, a fundamental
contradiction in the power delivery chain has existed between conventional

has therefore been an integral part of such systems to resolve this contradiction.

opportunities for much more energy efficient methods of power delivery.
performance of different power delivery mechanisms driving both asynchronous
and synchronous loads directly from a harvester source bypassing bulky energy
method, which employs a
energy from a EH circuit depending on load and source conditions, is developed.

Based on the novel CBB power delivery method, an asynchronous controller is

case study that is meant to explore relations between power path and task path.
To deal with different tasks with variable harvested power, systems may have a
