Title
Sensorless Optimization of Dead Times in DC–DC Converters With Synchronous Rectifiers
Abstract—This paper introduces an approach to achieve optimum
dead times in dc–dc converters with synchronous rectifiers
without sensing any of the power-stage signals other than the
output voltage. The dead times are adjusted adaptively to minimize
the duty-cycle command, which results in maximization of
the converter efficiency. The method is particularly well suited for
digital controller implementation, requiring no additional analog
components or modifications of standard gate-drive circuitry.
Experimental results for a digitally controlled 5 V-to-1 V, 5-A synchronous
buck converter demonstrate practical implementation
of the sensorless dead-time optimization algorithm.
Index Terms—DC–DC converter, dead time, synchronous rectifier,
