Definitions

  • the object of the invention is in particular to provide a generic household appliance device with improved properties in terms of switching behavior.
  • the object is solved by the characterizing features of claims 1 and 13, while advantageous embodiments and further developments of the invention can be taken from the dependent claims.
  • the home appliance device may further comprise a Control unit, an inverter and / or at least one heating element, in particular at least one inductor include.
  • the inverter is preferably provided to provide and / or to generate an oscillating electrical current, preferably with a frequency of at least 1 kHz, in particular of at least 10 kHz and advantageously of at least 20 kHz, in particular for operation of the at least one heating element.
  • the inverter comprises the switching unit.
  • the at least one parameter could, for example, be given by an inductance value of the bootstrap unit.
  • the at least one parameter preferably corresponds to a capacity value and / or an effective capacity value of the bootstrap unit.
  • the matching unit comprises at least two capacitors or at least two resistance components which are connected in series in at least one operating state, in particular in the start operating state and / or the continuous operating state.
  • the home appliance device can be adapted in particular flexibly to different requirements.
  • the converter units 50, 52 are further equipped with an undervoltage cut-off protection (UVLO). Consequently, the converter units 50, 52 are inoperative at a supply voltage below a limit value, in particular at the supply voltage terminals.
  • the limit value is between 9 V and 16 V.
  • the converter units 50, 52 are thus provided, in an operating state in which a voltage applied to the supply voltage terminals exceeds the limit value, to amplify a voltage signal of the control unit 36 applied to the converter input ,
  • a variable R boat corresponds to the resistance value of the bootstrap resistor 62, while a variable C boot corresponds to the capacitance value of the bootstrap capacity 60.
  • the matching unit 18a includes a zener diode 84a.
  • the Zener diode 84a is formed as a blocking element.
  • the Zener diode 84a is provided to block the bypass switch element 28a below a voltage limit of about 12V.
  • the matching unit 18a includes a resistor 86a which sets an operating point of the lock-up switching element 28a.
  • FIG. 5 a further embodiment of the invention is shown.
  • the embodiment of FIG. 5 the letter b is added.
  • the further embodiment of the FIG. 5 differs from the previous embodiments by a bootstrap unit 16b.
  • FIG. 8 a further embodiment of the invention is shown.
  • the embodiment of FIG. 8 the letter e is readjusted.
  • the further embodiment of the FIG. 8 differs from the previous embodiments by a bootstrap unit 16e.
  • FIG. 8 shows a cascaded bootstrap capacity 60e.
  • the bootstrap capacity 60e consists essentially of n consecutively connected bootstrap capacities 60b FIG. 5 Wherein the first capacitors 20e 1 - n 20e, 84e, the Zener diodes 1 - n, and the resistors 84e 86e 1 - 86e have n such varying values that a charging time constant T, at least during a starting operation state is continuously increasing.
