    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: The present invention relates to an integrated cooling system for a vehicle. The system includes an engine cooling loop having a first fluid configured for circulation through an engine of the vehicle and a power electronics cooling loop having a second fluid configured for circulation through at least one power electronics component of the vehicle. The engine cooling loop is fluidly isolated from, and in thermal communication with, the power electronics cooling loop.
