Abstract: An electrical transformer system using helical electrodes applied to a plasma. Systems and methods transform DC voltages and currents to different DC voltages and currents. Instead of using wires and iron cores similar to known transformers, the present DC to DC transformer system exploits plasma, helical electrodes, an axial magnetic field and radial magnetic field coils, with a control system to specify a radial magnetic field at the edge of a specified magnitude. A DC input voltage is applied, and an output is taken from electrodes at opposite the ends of the central apparatus. The system and apparatus contains a radial magnetic field embedded in the helical electrodes; the secondary current is taken from either solid or split (slotted) electrodes. Methods are disclosed for changing the output voltage and current relative to the input values. The system can function as either a stepup or a stepdown transformer.

Abstract: An apparatus and corresponding systems and methods for managing electric power, particularly a transformer system and method, and more specifically a transformer for direct current. An example apparatus includes a chamber configured to contain plasma. The apparatus includes input electrodes disposed at least partially within the chamber, and configured to receive a first direct current input into the chamber. The input electrodes are configured to cause the input direct current to induce motion in the plasma. Motion induced in the plasma transforms current flowing there-through. At output electrodes extend from the chamber. The output electrodes conduct a second direct current, from the induced motion in the plasma, for delivery from the chamber.

Abstract: An apparatus and corresponding systems and methods for managing electric power, particularly a transformer system and method. An example apparatus includes a chamber configured to contain plasma. The apparatus includes at least two input electrodes disposed at least partially within the chamber, and configured to receive an alternating current into the chamber. The input electrodes are configured to direct the alternating current to induce motion in the plasma. The apparatus also includes at least two output electrodes extending from the chamber. The output electrodes are configured to conduct a direct current, from the induced motion in the plasma, for delivery from the chamber.

Abstract: To prepare a thermally sprayed composite material, a precomposited powder is first prepared and then thermally sprayed at an ambient pressure of no less than about 0.75 atmosphere in an oxidation-preventing atmosphere. The precomposited powder has a plurality of powder particles, and each powder particle is formed of a matrix and reinforcing particles distributed within and encapsulated by the matrix. The matrix has a composition of a matrix metal such as molybdenum, hafnium, zirconium titanium, vanadium, niobium, tantalum, or tungsten, and a matrix non-metal of silicon, boron, or carbon. The reinforcement particle is silicon carbide, boron carbide, silicon nitride, or boron nitride.

Abstract: A mass of molybdenum disilicide-silicon carbide composite material is prepared by providing a mixture of molybdenum disilicide-silicon carbide precomposited powder, and plasma spraying the precomposited powder onto a substrate using argon-shrouded plasma spray deposition, to form a plasma-sprayed mass. The plasma-sprayed mass may be subsequently heat treated.
