Latest Patents

Shunquan Hu holds a patent for a "Neutral-point voltage balance control method and system for three-level converter in full power factor range." This patent describes a method that utilizes a large, medium, and zero vector modulation technique to synthesize a reference voltage vector. The method involves obtaining a voltage difference between two dc-link capacitors and using this difference as a neutral-point potential for the three-level converter. By selecting a small vector based on the neutral-point potential and updating the duty cycles of each basic vector, the system effectively controls the power switch of a three-phase bridge arm. The amplitude of the common-mode voltage of the NPC three-level converter is equal to one sixth of the dc-link voltage.
