Latest Patents
Oskar holds a patent for a groundbreaking invention titled "DC bus ripple elimination for multiphase electric machines." This patent describes a multiphase electric motor system and a method for controlling it. The method involves modulating a plurality of carrier signals with modulation signals to generate a multiphase motor supply signal. This signal includes a modulated phase signal for each phase of the electric motor. By defining a set of time windows in each period of the multiphase motor supply signal, Oskar's method allows for the modification of selected modulated phase signals. This is achieved by delaying the associated carrier signal in each time window, resulting in a shifted multiphase motor supply signal that effectively reduces DC bus ripple. This innovation enables the use of smaller filter capacitors in electrical motor systems, thereby improving overall efficiency.
