- Abstract
- In this paper, we proposed charge pump system designed specifically for energy harvesting at low voltage and low frequency, focusing on the twistron, a carbon nanotube yarn-based harvester. The whole system is composed of a transformer, a voltage doubler, and the charge pump system. Through simulations, we demonstrate that the charge pump system is capable of generating output voltage from 3.97 V to 4.47 V for the load resistance with 10 kΩ 1 MΩ when the input voltage of the charge pump system is set to 1.03 V. The measured power conversion efficiency (PCE) reaches up to 79%.
