Title: Ashkan Nami and Voltage Source Converter Control
Introduction
Ashkan Nami is an inventor associated with Vasteras, Sweden. His patent work concerns controlling cells in modular multilevel converters, which are used in voltage source converters.
Latest Patents
Nami is associated with 1 patent: “Method for Controlling Operation of a Cell in an MMC.” The invention describes a method for responding to a predetermined fault in a converter cell. Depending on the arm’s average current over a fundamental-frequency period and the converter’s operating mode, the method injects a predefined circulating current. It then identifies a period when the arm current flows in the specified negative direction and controls a bypass switch to close during that period. The application also describes a control unit and a voltage source converter.
