Abstract :
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. A novel modulation strategy for ML-VSCC, sample time staggered space vector modulation (STS-SVM), is adopted. The equivalent switching frequency is improved and the harmonic component is greatly decreased under this technique. An active power filter with this technique has been simulated. It can be verified that this technique is very promising.
