Tree Topology Charge Pump Design for Microscale Energy Harvesting

Summary

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.
