Abstract: A system includes a magnetic material supply for regulating a magnetic material flow rate of a magnetic material and a binder material supply for regulating a binder material flow rate of a binder material. A nozzle is configured for depositing a deposition mixture of the magnetic material and the binder material on a surface and a preheater is configured to preheat the deposition mixture before depositing on the surface. A controller is in operative communication with the magnetic material supply, the binder material supply, and the preheater. The controller is configured to receive an inductor core design file that represents a geometry and a magnetic permeability distribution of an inductor core, move the nozzle to one or more deposition locations, and adjust the magnetic material flow rate to the binder material flow rate to achieve a deposition mixture having a desired magnetic permeability at the deposition locations.

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.
