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.

Abstract: A power converter includes a plurality of switches that interconnect first and second input terminals of the power converter with first and second output terminals of the power converter. The switches are switched to convert power from the input terminals to the output terminals. During the switching, voltage spikes are mitigated by a first RLC branch connected from the first input terminal to the first output terminal and by a second RLC branch connected from the second input terminal to the second output terminal.
