Abstract
A multi-transformer LLC (resonant) power converter having at least two transformers including a first Tand a second transformer Tin series includes a switch network configured for receiving input power including a first and second switched node. Resonant circuitry is coupled between the first and second switched node including a series combination of an inductor, a capacitor, a primary winding of Tand a primary winding of a T. At least one switch is operable for providing a first mode that includes Tin the resonant circuitry and a second mode that excludes Tfrom the resonant circuitry. Secondary windings of Tand Tare connected electrically in parallel for driving an output capacitor (Co) through respective rectifiers which provide conversion from AC to DC.
