Voltage control of medium to high power three-phase inverter supply systems
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: In this thesis a new voltage control method is developed for a three-phase inverter
supply system. The inverter supply system consist of a Permanent Magnet Generator, a
three-phase rectifier, a three-phase ...
Analysis and design of a voltage regulator based on an AC-to-AC converter
(Stellenbosch : Stellenbosch University, 2003-04)
ENGLISH ABSTRACT: This thesis discusses the analysis and design of a voltage regulator based on
an AC-to-AC converter. A background study was performed on the best
topology for the purpose. The chosen topology was ...
Opportunities for in-line, transistorbased technologies on MV and LV power distribution networks
(Stellenbosch : Stellenbosch University, 2000-12)
ENGLISH ABSTRACT: Once more opportunities exist for innovative technologies to be applied on MV and LV
power distribution networks to meet the new challenges set by government through its
National Electrification Programme ...
Control of a 1.5 MW active power filter and regeneration converter for a Spoornet DC traction substation
(Stellenbosch : University of Stellenbosch, 2005-03)
Although regenerative braking has been in used in railway systems for a long time
already, the energy generated was dissipated in resistor banks. The rapid advances
in the power electronics field, accompanied by the ...
Active capacitor voltage stabilisation in a medium-voltage flying-capacitor multilevel active filter
(Stellenbosch : University of Stellenbosch, 2005-03)
A switching state substitution must be developed that will make use of both single-phase
redundancies and three-phase redundancies in the flying-capacitor topology. Losses should
be taken into consideration and the ...
Bidirectional converter for a stirling energy system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: This thesis discusses a 23 kW three-phase AC bus system that is utilized together with the
“Stirling Energy System (SES) Integrated Solar Dish-Stirling Module” to function as a
mini-grid for off-grid ...
A three-phase AC/AC matrix converter system
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The thesis discusses the analysis and design of a three-phase-to-three-phase direct
AC-AC matrix converter. A background study of the various matrix converter topologies
and their modulation strategies ...
