Abstract :
A new design method for the control implementation of a combined series-shunt active power filter (load compensation active conditioner, LCAC) for electrical power quality improvement is proposed. This active conditioner allows to cancel source voltage harmonics, to symmetrize the supply voltage, and to eliminate current harmonics and reactive/unbalanced load currents. The study of the higher harmonics passive filtering behaviour has permitted an enhancement of the compensating performance of the active conditioner. Practical case results are presented to support the performance of the new control design.
