A Space Vector Modulation Based Three-level PWM Rectifier under Simple Sliding Mode Control Strategy

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.
