Popis: | In Z-source topologies, a high-amplitude common-mode voltage can occur when shoot-through states are inserted. In this study, a new space vector pulse-width modulation for an active quasi-Z-source topology is proposed to operate at a high modulation index and reduce the common-mode voltage to one-third of the DC-link voltage. Moreover, the quality of the output voltage is improved by operation with a high modulation index and decreasing the switching loss of the H-bridge switches. The detailed operating principles of the active quasi-Z-source topology using the proposed space vector modulation (SVM) method are presented. A simulation model was built, and an experimental prototype was verified to correct the theoretical analysis. |
