Abstract
Abstract:
Static power converters produce harmonics due to the
nature of the conversion process. This paper will investigate two
variations of current mode control for three-phase power
converters ensuring reduced harmonic pollution and power factor
improvement. The first method employed uses a Fryze current
reference and the second method utilises a balanced three-phase
sinusoidal reference. Both control techniques are simulated under
unbalanced and distorted supply conditions using the PSIM
simulation platform. The results are presented showing that
using the Fryze current reference is the best choice.
