Abstract
Owing to the problems of DC side capacitor value choice in the application of Active Power Filter (APF), this
article presents a technique based on the analysis of the ripple voltage in DC side by graining appropriately the undulation
control rate within the range of settings and control DC voltage so that the voltage fluctuation rate can reach minimum
value under the condition of specific capacitance which is aimed at getting good compensation effects. In order to achieve
the stability of the DC side capacitor voltage control, we introduce a new technique on the DC output voltage deviation
square values of adaptive fuzzy PI control. Meanwhile, a Space Vector Pulse Width Modulation (SVPWM) is used to
conduct optimization design for the DC side voltage waveform. The simulation results show that using this method reduces
the DC voltage ripple and achieves steady DC output voltage.
