Common-mode voltage control through vector selection in three-to-five phase matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multi-phase matrix converters (more than three phase) are distinctively advantageous as because of reduced per-phase current and unity power factor operation. The electrical motors supplied through these converters do have ...
Space vector pulse width modulation scheme for three to seven phase direct matrix converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to seven-phase direct matrix converter (DMC). The modulation is based on the control of ...
Space vector model of a three-phase to five-phase AC/AC converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2013 , Conference Paper)
Multi-phase motor drives becoming popular in some niche application areas such as ship propulsion, 'more electric aircraft' electric and hybrid electric vehicle. The rise in popularity is attributed to fact that they are ...
Space vector PWM for a three-phase to six-phase direct AC/AC converter
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper a generalized multi-phase space vector theory is considered for developing the space vector modulation of a three-phase to six-phase AC to AC converter. The modulation is based on the control of the voltage ...
On the application of αβ-transformation for power systems frequency relaying
(
Institute of Electrical and Electronics Engineers Inc.
, 2001 , Conference Paper)
This paper presents a new and very accurate algorithm for power system frequency measurement. The proposed algorithm is based on αβ-transformation of the three phase voltages or current waveforms in the relay location, ...
PWM scheme for dual matrix converters based five-phase open-end winding drive
(
IEEE
, 2013 , Conference Paper)
The paper present simple carrier-based pulse width modulation scheme for three to five-phase matrix converters feeding a five-phase machine from both ends. The two matrix converters feeding a five-phase induction machine ...
On-line estimation of transformer model parameters
(
IEEE
, 2004 , Conference Paper)
The conventional method for determining the parameters of the transformer is to performing the open and short-circuited tests. The method is only suitable for off-line application. This paper presents an alternative approach ...
Ion beam modification of surface properties of polyethylene
(
Elsevier
, 2003 , Conference Paper)
Improvement of polymer tribological properties is an essential issue for their application when used as parts of machines or artificial human joints. Ion implantation is a very promising technique in this respect. This ...
Mechanical and thermal properties of gamma-ray irradiated polyethylene blends
(
Elsevier
, 2003 , Conference Paper)
In this work, the results obtained by gamma-ray irradiation of polyethylene (PE) blends are presented. The blends were produced by injection molding at 220°C with different compositional ratios, i.e. 100/0, 15/85, 25/75, ...
Compositional transformations in ion implanted polymers
(
Elsevier
, 2005 , Conference Paper)
Changes of surface layer composition produced by ion bombardment of polyethylene and polypropylene samples were studied. These materials are under consideration for load bearing surfaces in biological and technical ...
