Latest Patents

Martin Bruha holds a patent for a groundbreaking invention titled "Switching an Electrical Voltage Source Converter." This patent describes an electrical converter that features at least two output phases, incorporating a rectifier and a thyristor-based inverter interconnected by a DC link with an inductor. The thyristor-based inverter includes a half-bridge with multiple half-bridge arms for each output phase, with each arm being equipped with a thyristor. The method for switching the electrical converter involves cyclically switching the thyristors of the inverter, allowing for simultaneous activation of two thyristors from different half-bridge arms at specific time instants. This innovative approach ensures that the pulse number, which dictates the switching frequency of the thyristors during one stator voltage period, remains lower than the number of half-bridge arms of the inverter. Martin Bruha's invention is a testament to his expertise and creativity in electrical engineering.
