A multilevel voltage source cascade converter (ML-VSCC) using a carrier phase-shifted SPWM (CPS-SPWM) technique has been proposed. Compared with the traditional multi-level converter, this kind of converter utilizes fewer power switches and has a balance load, a good linearity between input and output and a perfect control feature.

The cascaded H-bridge (CHB) multilevel inverters are recognized as the most suitable topology for high-power medium-voltage power quality conditioning applications. This paper presents the effective controller design methodology for the CHB-based active power filters, which achieves dynamic reactive power compensation and harmonic mitigation.
