In this paper, a novel control strategy of multilevel shunt active power filter is presented. The idea behind the proposed control scheme is to combine the backstepping control and direct power control with virtual flux concept into one controller able to improve the performance of active power filter. The choice of the multilevel topology leads to a clear enhancement in the compensation of the polluting...
In this paper a new algorithm of three-level three dimensional space vector modulation (3DSVM) is presented for three-level four-leg diode-clamped inverter. The proposed algorithm can reduce remarkably the complexity of 3DSVM by using two sectors only (sector one and sector two) in the conception of all modulation algorithm steps such as: determination of the space vector location, duration time calculation,...
In this paper, a nonlinear backstepping controller is proposed for control a back-to-back high voltage direct current system using three-phase three-level voltage source converters (VSC-HVDC). The mathematical model and backstepping controller structure is discussed in a synchronous rotating reference frame (d-q) in the aim to provide high dynamic performance with complete decouple control of active...
