Résumé:
In recent years, the consumption of electric power has increased due to the high demand
of equipment, many of them of high power. Some of these equipments are the electric
arc welding machines, whose composition is transformers with low power factor, causing
a high consumption of reactive and providing high rates of harmonic distortion (TDH).
The purpose of this work is to analyze, design, simulate and test a CA-CC converter as
a power factor pre-regulator (PFC), the topology used for this study was the isolated
double-switched zeta converter for use in arc welding by coated electrodes. Analyzes of
the zeta converter were carried out in the continuous (CCM) and discontinuous (DCM)
conduction mode, the project design and simulation results were presented.
