Abstract :
The control system for Cascaded H-bridge (CHB) converter is proposed in this paper. The converter output voltage is controlled using a Space-Vector Pulse Width Modulation (SV-PWM). The DC-link voltages are controlled by appropriate choice of H-Bridges, used to output voltage generation. The simulation researches of two multilevel CHB rectifiers are presented. These rectifiers were utilized to coupling of two AC grids. Proposed control strategy allows to good voltage stabilization on the DC-link capacitors.
