Abstract:The causes of DC-side voltage ripple in a shunt hybrid active power filter are analyzed. Aiming at the effects of the voltage ripple on system performance, the method to ensure stability of the voltage at DC-side and to improve overall performance of system is put forward by using fuzzy-PI controller. The concrete realizing method of gaining systematic reference signals is provided. This controlling method offers high capability of dealing with nonlinear and undetenninistic process. It features simple algorithm, no extra complex hardware needed, and is an economical solution. Experimental results have testified the validity of this method.
Keywords:Hybrid active power filter Voltage at DC-side Voltage stability Fuzzy-PI
