Resumen
Technological advances occurred in the past decades show the quest of mankind for
better quality life conditions. All the development achieved in different areas of human
knowledge, in many cases, are directly related to the use of electricity. Research related to
the generation of electricity and about the ways electricity can be used is a very important
and actual area. This work has the purpose to introduce the use of an impedance source
converter to feed single-phase loads from a primary feed system, operating in standalone
mode. The converter has an impedance network at the input terminals composed by an ultra
fast diode, inductors and capacitors. There are used four power switches to convert DC
power to AC power. The input voltage in Z-network is synthesized using a set composed
by an adjustable AC voltage source, a three-phase rectifier bridge and a larger electrolytic
capacitor of filter. A guide line for the design of power converters and output filters, as
well as simple boost modulation technique and its variations will be presented. Besides
that, a new modulation technique will be proposed. Also simulation and experimental results
about the modulation techniques used to drive the impedance source converter will
be presented.
