A dynamic dead time controller for synchronous dc-dc converters is presented. It was specifically designed to operate in a boost stage based on GaN FETs switching at frequencies in the MHz range, but its analog circuitry can be easily modified to accommodate other switch technologies and converter topologies. Experimental tests were carried in the presence of wide variations of the operating conditions, demonstrating stable dead time duration in the few nanoseconds range.

Abstract
A dynamic dead time controller for synchronous dc-dc converters is presented. It was specifically designed to operate in a boost stage based on GaN FETs switching at frequencies in the MHz range, but its analog circuitry can be easily modified to accommodate other switch technologies and converter topologies. Experimental tests were carried in the presence of wide variations of the operating conditions, demonstrating stable dead time duration in the few nanoseconds range.| File | Dimensione | Formato | |
