A forward DC/DC converter using semi-synchronous MOSFET rectifiers with a peak detector and a pulse transformer. In another example edge triggered circuits and active clamps are used. The gate driving signal for one MOSFET is derived from the secondary of the input power transformer, but the second MOSFET gate is driven from a combination of the secondary of the input power transformer and the pulse transformer. The second MOSFET remains on during the core reset and dead time periods thereby providing a low voltage current path for the load current.
