Latest Patents

One of Adnan's latest patents is titled "Power converter arrangement and control method therefor." This invention involves a method for controlling a converter assembly that includes a line-commutated converter. The converter has an alternating voltage terminal that can connect to an alternating voltage network. The assembly also features a switch module branch arranged serially in the phase conductor, which contains a series circuit of switch modules. These modules can generate bipolar voltages that add up to a branch voltage. The connection voltage to a point between the switch module branch and the converter is controlled by adjusting the amplitude of a positive sequence component of the branch voltage.

Another significant patent is related to "Operating a multilevel converter." This method involves a multilevel converter with multiple phase modules, each containing three phase module branches. The switching device of each phase module connects the alternating voltage connection to different connection points based on the switching position. The method effectively controls circulating currents of the multilevel converter according to total and differential energy variables of the phase modules, ensuring energy balance between the branches.
