摘要：

This paper proposes a novel power balancing control scheme for the cascaded H-bridge (CHB) DSTATCOM. The principle of the carrier phase-shifted pulse-width modulation (CPS-PWM) and the mathematical model of the CHB-DSTATCOM are presented. The power balancing mechanism and the stable control region are analyzed using the phasorial diagram representation. The current loop controller is designed by using root locus approach, and the dc-link voltage balancing controller is synthesized based on the devised power balancing mechanism. The simulation results obtained from the alternative transient program (ATP) are presented and evaluated. The validity and effectiveness of the control scheme is confirmed by the simulation and experimental results.
