Abstract :
Operation of voltage-source inverter with fully controlled front-end stage supplied from an unbalanced power grid has been investigated and analyzed. A method of finding optimal switching functions based on various optimizing criteria has been investigated that generates the demanded output DC-link current. The overall power factor and current unbalance have been used as the optimizing criteria. The individual cases were simulated by a numerical model
