Abstract
This paper proposes a Self-Reset Zero-Current Switching (ZCS) Circuit for thermoelectric energy harvesting. The Self-Reset ZCS circuit minimizes the operating current consumed by the voltage comparator, thereby reduces the power consumption of the energy harvesting circuit and improves the energy conversion efficiency by adding the self-reset function to the comparator. The Self-Reset ZCS circuit shows 3.4% of improvement in energy efficiency compared to the energy harvesting system with the conventional analog comparator ZCS for the output/input voltage ratio of 5.5 as a result of circuit simulation. The proposed circuit is useful for improving the performance of the wearable and bio-health-related harvesting circuits, where low-power and energy-efficient thermoelectric energy harvesting is needed.
