一种用于公用事业规模可再生能源并网的软开关高频链单级三相逆变器

A novel single-stage high-frequency link three-phase (3φ) inverter along with a modulation strategy is presented in this paper. The topology is targeted for grid integration of utility scale renewable and alternative energy sources like solar, fuel cell, and wind, where the power flow is unidirectional (from dc to ac). The primary side converter has a 3φ voltage source inverter (VSI) structure alo...
