Discrete stationary frame control for a front-end converter

Abstract

Discrete stationary reference frame current controllers are described in terms of their closed loop state space representations and their transient performance and stability studied through average model based analysis for L-filter and LCL-filter based Voltage Source Converter (VSC). The stationary reference frame control for the VSC is then verified through simulations for an active filter application with the switching model in Matlab/Simulink.
