A synchronous rectifier for isolated forward DC-DC converters, integrated in a high-voltage smart-power IC technology Universiteit Gent
The synchronous rectifier in isolated forward DC-DC converters is traditionally built with discrete DMOS power transistors driven directly from the secondary winding of the pulse transformer. Unfortunately, this technique induces very high switching losses, especially at high switching frequency. This paper presents a new synchronous rectifier topology that drives the DMOS devices in a much more power-efficient manner, employing an additional ...
