Abstract
This paper presents a low power boost converter using offset controlled Zero Current Sensor (ZCS) control for thermoelectric energy harvesting.[1] [5] Offset controlled ZCS uses adjustable pre-offset that is controled by 6bit code each connected gate of NMOS for switching. Offset controlled ZCS demonstrates an efficiency that is higher than using analog comparator ZCS and that is smaller area than using delay line ZCS. Experimentally, the offset controlled ZCS system consumes 10 times less power than analog comparator ZCS based system at similar performance.
