  • GENERALIZED MULTILEVEL CONVERTER CIRCUIT TOPOLOGY WITH SWITCHED CAPACITORS
    Publication number: 20230344368
    Abstract: A method for arranging a generalized multilevel converter switching topology with switched capacitors for converting DC current into AC current, wherein the arrangement can be configured with regard to predetermined output voltage levels. With the same number of semiconductor switches, a higher number of voltage levels can be achieved in comparison to previous methods. Depending on the given problem, a maximum output voltage of the AC current may vary from significantly lower values than the input voltage of the DC current up to a multiple of these values. The generalized circuit topology may be adapted to a desired number of voltage levels by a repeatable arrangement of voltage level units that can be arranged in a row and to a multiphase load by a corresponding selection of a number of sub-modules. Furthermore, a modular multilevel converter configured with the circuit topology is described.

  • Hybrid interface testing
    Patent number: 11789854
    Abstract: A user interface testing system, method, and device for a vehicle under test (“VUT”). A test system is communicatively coupled to the VUT. A test system records outputs of at least one human-machine-interface (“HMI”) responsive to a first set of test cases and then scores the recorded HMI outputs responsive to the first set of test cases. The test system generates a second set of test cases and scoring criteria for the second set of test cases based on the received first set of test cases and the recorded HMI outputs responsive to the first set of test cases. The test system performs the second set of test cases on the HMI and records HMI outputs responsive to the second set of test cases. The test system assigns scores for the recorded HMI outputs responsive to the second set of test cases using the generated scoring criteria.
