    Abstract: A magnetic unit is presented. The magnetic unit includes a magnetic core. The magnetic core includes a first limb and a second limb disposed proximate to the first limb, where a gap is formed between the first limb and the second limb. The magnetic unit further includes a first winding wound on the first limb. Moreover, the magnetic unit includes a conductive element disposed facing an outer periphery of the first winding, where the conductive element is configured to control a fringing flux generated at the gap. Further, the magnetic unit includes a heat sink operatively coupled to the conductive element, where the conductive element is further configured to transfer heat from at least one of the conductive element and the first winding to the heat sink. Moreover, a high frequency power conversion system and a method of operation of the magnetic unit is also presented.

    Abstract: Systems and methods related to controlling flux through an inductor of a power converter are described. For example, a control system is configured to control a multi-level converter having a first leg, a second leg, and at least one inductor. The control system includes a processor operatively coupled to a memory. The processor receives a reference signal. The processor determine flux through at least one inductor of a converter. The processor controls a temporal distribution of the flux through the at least one inductor based on the flux through the at least one inductor according to the reference signal.

    Abstract: A direct current circuit breaker includes main circuit for carrying a main-path current, and a transient circuit for carrying a transient-path current. The main circuit includes a first solid state switch and a main contactor. The first solid state switch is coupled in series with the main contactor. The transient circuit is coupled in parallel with the main circuit. The transient circuit includes an auxiliary contactor coupled in series with a second solid state switch. The second solid state switch closes when the main-path current exceeds a first threshold. The first solid state switch then opens. The main contactor opens when the main-path current falls below a second threshold. Then the second solid state switch opens. The auxiliary contactor opens when the transient-path current falls below the second threshold and after the second solid state switch opens.
