Abstract

This paper presents an
imposed source current predictive control approach for a current source
rectifier that can be used as battery charger fed from three-phase ac grid. The
proposed MPC technique allows to charge the battery with a constant current or voltage
as what is required for cyclic charge process of batteries. The proposed
technique ensures unity input power factor operation for grid side. The
single-objective cost function of the predictive control employs the error
between supply current reference and supply current prediction and the
switching state that minimizes this cost function is selected among the nine
switching vector combinations of the current source rectifier so as to apply
for next sampling interval. An active damping current term, that is predicted
from the input filter capacitor voltage estimation is included in the cost
function to mitigate the resonance of input LC filter. The supply current
references in phase with grid voltages are generated from grid voltages and the
amplitude of this reference currents are generated from the charging
requirements of the battery. The input filter model is used to predict the
filter capacitor voltages at sampling intervals k and k+1 in order to eliminate
sensor requirement for them. A simulation study is carried out to observe the
proposed method in terms of steady-state and dynamic responses and supply
current quality.
