Abstract :
In this paper, switching modulation schemes for Z-source converters used for renewable energy integration are investigated. Both dc-dc converters and dc-ac converters are discussed. Input/output voltage relationships for the two types of converters (half-bridge dc-dc and three-phase three-bridge dc-ac) are analyzed based on circuit analysis. The two converters are built and simulated in PSCAD. Simulation results give validation of the analysis results.
