Tree Topology Charge Pump Design for Microscale Energy Harvesting
- 总结
- Purdue University researchers have developed a new charge pump design for use in microscale energy harvesting. The power converter is configured to transfer electrical energy from an energy transducer to energy storage device. This new converter design is effective at very low input voltages, from near zero to one volt, where conventional charge pumps fail. It also increases harvested power by at least 20 percent over existing power converters.

- *Background
- A key component of any energy harvesting system is the power converter, also known as a charge pump. A charge pump steps up the input voltage from a transducer to a higher voltage. Current microscale charge pumps see a sharp drop off in efficiency when input voltage from the transducers is very low (less than one volt).
