Abstract
Synchronous rectifier gate voltage boost method and system. At least some of the example embodiments are methods of operating a power converter to create an output voltage, including storing energy in a field of a main transformer arranged for flyback operation, the storing during periods of time when a primary switch is conductive and current flows through a primary winding of the transformer; and then transferring energy from the field of the main transformer to the output voltage on a secondary side of the power converter; activating a secondary rectifier (SR) switch on the secondary side of the power converter during periods of time when the primary switch is non-conductive, the activating by: driving a gate of the SR switch without boost if the output voltage is above a first threshold; and driving the gate of the SR switch with boost if the output voltage is below the first threshold.
