  • Patent number: 11949339
    Abstract: An electronic circuit arrangement for a fuel cell arrangement may include a first electrical voltage converter stage and a second electrical voltage converter stage. An electrical fuel cell voltage may be appliable to the first electrical voltage converter stage on an input side. The electrical fuel cell voltage may be convertible into a first electrical output voltage of the first electrical voltage converter stage via the first electrical voltage converter stage. The first electrical output voltage may be appliable to the second electrical voltage converter stage on an input side. The first electrical output voltage may be convertible into a second electrical output voltage of the second electrical voltage converter stage via the second electrical voltage converter stage. An electrical interconnection of the first electrical voltage converter stage and the second electrical voltage converter stage may be switchable between a first interconnection state and a second interconnection state.

  • Publication number: 20230288268
    Abstract: A method for determining a temperature of an Insulated-Gate Bipolar Transistor (“IGBT”) driver, the IGBT driver may include two Metal-Oxide-Semiconductor Field-Effect Transistor (“MOSFET”) elements, two direct voltage terminals for providing a base direct voltage for the two MOSFET elements, two gate terminals for providing two control voltages for the two MOSFET elements, a measurement output for outputting an output voltage, and an alternating voltage source for providing an alternating voltage, the method may include providing the control voltages, the base direct voltage, and the alternating voltage, superimposing the alternating voltage with the base direct voltage, capturing the output voltage at the measurement output of the IGBT driver, and determining the temperature of the respective MOSFET elements from the captured output voltage.
