Abstract: A power converter includes primary and secondary bridges, a transformer, and a controller configured to generate a switching mode map that correlates each of a plurality of switching modes to a respective set of value ranges of system parameters of the power converter. The sets of system parameter value ranges are contiguous and non-overlapping across the switching mode map, each of the plurality of switching modes includes gate trigger voltage timings for commuting at least one of the primary and secondary bridges. The controller is configured to obtain a plurality of measured system parameter values, select from the switching mode map one of the plurality of switching modes that correlates to the set of system parameter values containing the plurality of measured system parameter values, and adjust gate trigger voltage timings of at least one of the primary and secondary bridges, according to the selected switching mode.

Abstract: A controller for a power converter includes one or more controller modules operably linked to a transformer core of the power converter, to primary bridge switches of the power converter, and to secondary bridge switches of the power converter, wherein the one or more controller modules are configured to avoid saturation of the transformer core by modulating pulse widths of first electrical pulses sent to the primary bridge switches, based at least on measurements of DC components of current through primary and secondary windings adjacent the transformer core, and by modulating pulse widths of second electrical pulses sent to the secondary bridge switches, based at least on measurements of DC components of current through the primary and secondary windings.
