The CNM-Hypermultiplet Nexus [PDF]
, 1998 We consider additional properties of CNM (chiral-nonminimal) models. We show how 4D, N = 2 nonlinear sigma-models can be described solely in terms of N = 1 superfield CNM doublets.

A novel harmonic elimination PWM strategy
Seventh International Conference on Power Electronics and Variable Speed Drives, 1998 This paper presents a novel space vector-based PWM strategy which closely approximates in "real-time" the switching angles of the selective harmonic elimination PWM (HEPWM) strategy for inverters. The strategy uses only conventional regular-sampled techniques and does not require any of the intensive offline computations that are usually associated ...

New exact solutions for polynomial oscillators in large dimensions [PDF]
, 2003 A new type of exact solvability is reported. We study the general central polynomial potentials (with 2q anharmonic terms) which satisfy the Magyari's partial exact solvability conditions (this means that they possess a harmonic-oscillator-like wave ...

VSC Based D-STATCOM with Selective Harmonic Elimination
2007 IEEE Industry Applications Annual Meeting, 2007 This paper describes the design, implementation, and performance of a medium-size distribution-type static synchronous compensator (D-STATCOM) with the simplest two-level three-leg voltage-source converter (VSC) topology. Reactive-power control is achieved by phase-shift-angle control, and VSC harmonics are eliminated by selective harmonic elimination ...

Active harmonic elimination for multilevel converters [PDF]
IEEE Transactions on Power Electronics, 2006 This paper presents an active harmonic elimination method to eliminate any number of specific higher order harmonics of multilevel converters with equal or unequal dc voltages. First, resultant theory is applied to transcendental equations characterizing the harmonic content to eliminate low order harmonics and to determine switching angles for the ...
