Abstract

A high-current (60 A) low-voltage (1.5 V) DC/DC converter is designed and tested. Center-tapped and Current-doubler rectifiers are compared for high current fast dynamic applications. The selected topology is the half-bridge with current-doubler rectifier and single winding self-driven synchronous rectification (SWSDSR). This topology is very suitable for high-current low-voltage applications. However SWSDSR is successfully used only if all the parasitic inductances (transformer and layout) are minimized. Measured efficiency is 88% at full load 60 A
