ABSTRACT: In this paper, a voltage oriented control strategy for
three-level PWM rectifier based on Sliding Mode Control (SMC) is introduced in
order to obtain fast and accurate response of dc-bus voltage. To verify the
validity of the analysis and the feasibility of the proposed control method a
set of simulation tests have been conducted using Matlab/Simulink. The
simulation results show that compared to the conventional PI controller, the
SMC can reduce drastically the three-level rectifier’s voltage fluctuation and
improve the dynamic response of dc-bus significantly.
