Latest Patents
One of his latest patents is titled "Method for damping resonant component of common-mode current of multi-phase power converter." This patent describes a method and arrangement for damping a resonant component of a common-mode current in a multi-phase power converter. The method involves determining the common-mode current, forming a feedback signal based on this current, and injecting the feedback signal into a common mode current reference to dampen the resonance frequency component. A delay is added to the feedback signal to ensure it has a sufficient phase margin with respect to the subsequent cycle of the resonance frequency component.
Another significant patent is the "Switching arrangement for inverter, and inverter." This invention focuses on a method and switching arrangement for an inverter that includes a positive direct current pole, a negative direct current pole, and a neutral direct current pole. The arrangement features controllable switches connected between the neutral direct current pole and both a virtual neutral point and an earth potential of the alternating current network supplied by the inverter.
