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 ...
Transformerless series dip/sag compensation with a multilevel cascaded inverter
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This thesis covers the development of a multilevel cascaded inverter for the purpose of costeffective
transformerless series dip compensation. Of all known power quality problems, voltage
dips are the ...
A reliable telemetry software design for a satellite system
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: One of the requirements for satellite telemetry systems is the provision of reliable
telemetry data to allow accurate monitoring of the satellite status. This thesis focuses on
the design of telemetry ...
The comparison of AC and DC alternatives for sub-transmission networks
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: Recent advances in semiconductor technology extended the economic power range
for DC transmission to just a few MW. Network planners need tools to compare AC
and DC alternatives in order to find the ...
Design and evaluation of a 300 kW double stage axial-flux permanent magnet generator
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: This thesis deals with the design and evaluation of a 300 kW double stage axial-flux
permanent magnet generator with an ironless stator. The magnetic and electrical
design equations are derived for ...
