Abstract:
|
Shunt active power filters are devices, connected in
parallel with nonlinear and reactive loads, which are in charge of
compensating these characteristics in order to assure the quality
of the distribution network. This paper analyzes the dynamics of a
dc bus split-capacitor boost converter used as an active filter and
proposes a control system which guarantees the desired closedloop
performance (unity power factor and load-current harmonics
and reactive-power compensation). The proposed controller is hierarchically
decomposed into two control loops, one in charge of
shaping the network current and the other in charge of assuring
the power balance. Unlike previous works that appeared in the literature,
both control loops are analytically tuned. This paper describes
the analytical design of the controller and presents some experimental
results that show the good performance of the closedloop
system. |
