A Two-mode Buck Converter toward High Efficiency for the Entire Load Range for Low Power Applications
(Virginia Tech, 2015-11-05)
In order to extend the battery life of smart cameras, it is essential to increase the efficiency of power converters, especially at light load. This thesis research investigated a power converter to supply power for the ...
A Two-Phase Buck Converter with Optimum Phase Selection for Low Power Applications
(Virginia Tech, 2015-01-27)
Power consumption of smart cameras varies significantly between sleep mode and active mode, and a smart camera operates in sleep mode for 80 — 90% of time for typical use. To prolong the battery life of smart cameras, it ...
A Constant ON-Time 3-Level Buck Converter for Low Power Applications
(Virginia Tech, 2015-04-22)
Smart cameras operate mostly in sleep mode, which is light load for power supplies. Typical buck converter applications have low efficiency under the light load condition, primarily from their power stage and control being ...
Power Converter Design for Maximum Power Transfer and Battery Management for Vibration-Based Energy Harvesting on Commercial Railcars
(Virginia Tech, 2015-06-24)
Although the locomotive of a train is energized, in general, other railcars are not. This prevents commercial rail companies from installing sensor equipment on the railcars. Thus, several different solutions have been ...
