Abstract

This paper addresses boost converter circuits that are built for very low input voltages, i.e. less than 1 V. Such circuits can be useful for single-cell solar and fuel cell power supplies. Important issues are physical size, high conversion ratio, efficiency, and startup. Several experimental studies show the impact of these issues. A startup technique is proposed that works for arbitrarily low input voltages.
