Abstract

Taking the small signal stability analysis of three-phase Vienna rectifier AC cascade system as the research object

the simplified small signal stability criterion in dq coordinate system is put forward

further

a Vienna rectifier impedance equation for small signal stability analysis in cascade system is given. Finally

a virtual impedance method is proposed to improve the small signal stability of Vienna rectifier system. A complete simulation and test model is built

and the detailed theoretical analysis and design scheme of virtual impedance are given. The results show the correctness of the small signal stability analysis and the proposed virtual impedance method.
