Latest Patents
One of Hammer'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 is designed to connect to an alternating voltage network through a phase conductor. The assembly features a switch module branch that is arranged serially in the phase conductor, allowing for the generation of bipolar voltages that contribute to a branch voltage. The control method adjusts the amplitude of a positive sequence component of the branch voltage to manage the connection voltage effectively.
Another significant patent is the "Method for operating a power converter." This method pertains to a thyristor-based line-commutated multi-phase power converter connected to a multi-phase AC voltage source. The invention includes a series circuit of modules for each phase, which consists of electronic switching elements and an energy storage device. The system measures the voltages of the phases and generates additional voltage to counteract any detected undervoltage, thereby ensuring stable operation.
