Title: DC-AC electrical 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 transforming direct current to alternating 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 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. Output electrodes extend from the chamber, which output electrodes may rotated in a controlled manner. The output electrodes conduct a three or one phase alternating current, from the induced motion in the plasma, for delivery from the chamber.

Multiple DC, single AC converter with a switched DC transformer

Patent Donnelly, Matthew K [Kennewick, WA]; Hammerstrom, Donald J [West Richland, WA]

The invention is an improvement of the PASC inverter, wherein the improvements include the reduction from two shorting gates per transformer to one shorting gate per transformer and replacement of active control of the shorting gate with passive control of the shorting gate. Further advantages are obtained through the use of anti-parallel gate sets.

DC to DC electrical transformer

Patent Finn, John; Nebel, Richard; Moser, Keith; ...

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 amore » « less

Single phase bi-directional AC-DC converter with reduced passive components size and common mode electro-magnetic interference

Patent Mi, Chris; Li, Siqi

A bidirectional AC-DC converter is presented with reduced passive component size and common mode electro-magnetic interference. The converter includes an improved input stage formed by two coupled differential inductors, two coupled common and differential inductors, one differential capacitor and two common mode capacitors. With this input structure, the volume, weight and cost of the input stage can be reduced greatly. Additionally, the input current ripple and common mode electro-magnetic interference can be greatly attenuated, so lower switching frequency can be adopted to achieve higher efficiency.

Simultaneous distribution of AC and DC power

Patent Polese, Luigi Gentile

A system and method for the transport and distribution of both AC (alternating current) power and DC (direct current) power over wiring infrastructure normally used for distributing AC power only, for example, residential and/or commercial buildings' electrical wires is disclosed and taught. The system and method permits the combining of AC and DC power sources and the simultaneous distribution of the resulting power over the same wiring. At the utilization site a complementary device permits the separation of the DC power from the AC power and their reconstruction, for use in conventional AC-only and DC-only devices.
