Abstract
Official abstract text for this publication.
A multi-transformer LLC (resonant) power converter having at least two transformers including a first T 1 and a second transformer T 2 in 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 T 1 and a primary winding of a T 2 . At least one switch is operable for providing a first mode that includes T 2 in the resonant circuitry and a second mode that excludes T 2 from the resonant circuitry. Secondary windings of T 2 and T 1 are connected electrically in parallel for driving an output capacitor (Co) through respective rectifiers which provide conversion from AC to DC.
First claim
Opening claim text (preview).
We claim: 1. A resonant power converter, comprising: a switch network comprising a plurality of power switches configured for receiving input power having a time varying voltage Vin, said switch network providing a first switched node and a second switched node; resonant circuitry coupled to receive biasing provided by said first switched node, said resonant circuitry comprising in series combination an inductor, a capacitor, a primary winding of a first transformer (T 1 ) and a…
