The converter-modulator is a resonant power conditioning configuration that is optimized for a particular load impedance or parameter space. Although traction motor Insulated Gate Bipolar Transistors (IGBTs) are typically used for hard-switching appl

IECON'03. 29th Annual Conference of the IEEE Industrial Electronics Society (IEEE Cat. No.03CH37468).
Los Alamos has developed a new methodology and technique to generate high voltages (pulse or "DC") with a high average power, from a low voltage input source (e.g. +/-1.2 kV). We are using this recently developed technology for the Oak Ridge National

For feedback stabilization experiments the magnetic field in a 120$sup 0$ sector of the Scyllac torus has been lowered to 17 kG, and the plasma parameters adjusted accordingly to reduce the m = 1 instability growth rates to values which are compatibl
