Popis:	This paper discusses the dynamic interaction of multi active power filters (APFs) paralleled with a weak power grid. In order to analyze the dynamic interaction from multi APFs, the output impedance of an APF is solved. The influences of both circuit and control parameters on the output impedance are analyzed. Based on the output impedance of an APF, the dynamic influences of an APF on the other APF connected to the weak grid are discussed. As shown in this paper, the stability of an APF is improved with an increased output filter inductance and some control parameters to reduce its bandwidth. The proposed analysis methods can be used not only for multi APFs but also for the other multi-inverters connected to a weak grid. Experimental tests are carried out using two paralleled three-phase 10-kVA inverters to confirm the validity of the theoretical analysis.
