Finite set model predictive current control with reduced and constant common mode voltage for a five-phase voltage source inverter
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Conference Paper)
Multiphase drives are now becoming serious competitor to traditional three-phase drives due to reasons of better fault tolerant property and reduced per-phase converter rating that are especially suited to high power drives ...
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.
