Thesis (D. Tech. Engineering : Electrical ; Dept. Applied Electronics and Electronic Communications) -- Vaal University of Technology / Two methods to convert an AC current source to an AC voltage source are presented.
Both methods make use of a current transformer to provide energy extraction from
the main system while maintaining galvanic isolation between the main system and
the output system. Control is via a pulse width modulation scheme in both instances.
The ftrst method uses a storage element to provide a DC voltage, which feeds an
inverter that supplies the AC load with a voltage source. The second method does
not use a storage element but is a direct AC current source to AC voltage source
converter employing a current transformer. This has not been done before.
A possible application of this study is in the extraction of power from high voltage
transmission lines without the conventional substation and rural grid to supply small
users such as the telecommunication industry.
