A carrier-based approach for overmodulation of three-level neutral-point-clamped inverter with zero neutral-point current

2012 IEEE Energy Conversion Congress and Exposition (ECCE), 2012
In a voltage source inverter, overmodulation is required to extend the range of operation and enhance the dclink voltage utilization. A carrier-based implementation of a modulation strategy for the three-level neutral-point-clamped inverter is proposed for the overmodulation region.

Neutral-Point Voltage Reduction

2017
A three-level converter has two DC-links and it makes output voltage with three levels. If the two DC-link voltages are not the same, the output voltage is distorted.

On the neutral points in Rayleigh transfer

Journal of Quantitative Spectroscopy and Radiative Transfer, 2017
Abstract In this paper we consider the dependence of the existence and position of the neutral points on the albedo of single scattering and the optical thickness in a Rayleigh scattering plane-parallel homogeneous atmospheres. We use the Chandrasekhar method of discrete ordinates and the method of approximating the Sobolev resolvent function to ...

On the location of the magnetopause neutral points

Journal of Geophysical Research: Space Physics, 1986
We have studied the configuration of the polar cusps in a static MHD equilibrium model. By introducing two quasi‐linear equilibrium models, we show that one can obtain magnetospheric configurations with the magnetopause neutral points located tailward of the earth and at the same time with reasonable tail magnetic field geometry.
