Abstract
A DC to DC power converter device includes a controller, and a DC to DC resonant converter that includes first and second full bridge chopper circuits (FBCCs) and an LLC resonant converter coupled between the first and second FBCCs. To cause the DC to DC resonant converter to operate in a conversion mode where an input voltage received by the second FBCC is converted to an output voltage provided by the first FBCC, the controller controls switches of the second FBCC and switches of the first FBCC to transition between an ON state and an OFF state with the ON state reoccurring at a frequency lower than a resonant frequency of the DC to DC resonant converter, so that the output voltage can be higher than the input voltage.
