US Patent 11496056 Parallel branched resonant converter

This disclosure describes systems, methods, and apparatus for driving a plurality of output circuits from a DC input signal using a resonant converter, the resonant converter comprising a switch network, a resonant tank, and a rectifier network, the resonant tank comprising: a resonant capacitor bridge coupled across the switch network; a plurality of branches, each branch comprising at least one series inductor coupled at a first end to the resonant capacitor bridge and at a second end to the rectifier network; and at least one parallel inductor; the rectifier network comprising one or more groups of transformers, each group coupled to one branch of the plurality of branches, and wherein the primary windings of the transformers of each group are coupled in parallel, and wherein the secondary windings are configured for coupling to an output load.
