The retardation responses at various positions of the phase shifter are calculated from molecular orientation distribution response under application of bias voltage. The rise time drastically increases outside the center conductor. On the other hand, the decay time is almost constant. The relation ...
DC bus voltage balancingThis article presents space vector modulation of line-to-line voltage for the three-phase neutral-point clamped n-level converter with DC-link capacitor voltage balancing using redundant vectors. The developed modulation strategy is based on an equivalent matrix structure of ...
