This paper proposes an optimal control strategy for an HVdc light system using a direct current vector control mechanism. The proposed approach is compared with the traditional vector control method for different HVdc control requirements, su

This paper proposes a new and explicitly frequencyadaptive method for Virtual Flux estimation and voltage sensorless grid synchronization under unbalanced conditions.

The existence of the modules capacitors necessitates the control of their voltage level. A dedicated controller is described that has two main parts the averaging controller that takes care of the average capacitor voltage level per leg and the b
