Hybrid Damping in Higher Order Line Side Filter in Active Front-end Operation

Nilanjan Mukherjee and Vinod John

Abstract—Active front-end converter draws a special attention in drives application and distributed generation application where good power quality and robustness are essential. Damping is an essential part of design in LCL filter based grid-connected system from point of view closed loop stability. This paper presents a novel concept of state-space based hybrid-damping technique, which is an appropriate combination of passive and active damping, in order to make grid-interconnection reliable and robust which can ensure adequate stability margin in all possible grid interactive conditions.

Index Terms—Active front end converter (AFEC); hybrid damping; state-space based analysis; LCL filter.
