  • Method and device for charging an intermediate circuit capacitor in a high-voltage network
    Patent number: 12337708
    Abstract: The invention relates to a method (100) for charging an intermediate circuit capacitor (210) in a high-voltage network (205). The high-voltage network can be connected to a power source (220) by means of at least one switch (230) and is coupled to a low-voltage network (295) by means of a DC voltage converter (250). The method comprises the steps: determining (110) a first voltage (U1) across the power source (220); determining (120) a second voltage (U2) across the intermediate circuit capacitor (210); determining (130) a first difference (D1) between the first voltage (U1) and the second voltage (U2); switching (140) the DC voltage converter (250) to the boost converter operating mode to charge the intermediate circuit capacitor (210) according to the determined first difference (D1).

  • Device and method for providing a signal having an adjustable pulse duty factor
    Patent number: 10158347
    Abstract: The invention relates to a device and to a method for producing a signal having an adjustable pulse duty factor, in particular a pulse-width-modulated signal. For this purpose, the period duration of the pulse-width-modulated signal can be varied. Thus, the pulse duty factor of the pulse-width-modulated signal can be adapted very accurately to the desired pulse duty factor without great switching complexity by using a simple counter with a fixed clock frequency.
