Abstract
The invention relates to a circuit arrangement, having: a comparator device for comparing a value of an electrical input voltage with an upper threshold value and/or with a lower threshold value; an increasing device for increasing an electrical output voltage if the comparison by the comparator device shows that the value of the input voltage is greater than the upper threshold value; and a reducing device for reducing the electrical output voltage if the comparison shows that the value of the input voltage is less than the lower threshold value.
Claims18
A circuit arrangement, comprising:
- a comparator device for comparing a value of an electrical input voltage to an upper threshold value and to a lower threshold value;
- an increasing device for increasing an electrical output voltage when a comparison by the comparator device shows that the value of the input voltage is greater than the upper threshold value;
- and
- a reducing device for reducing the electrical output voltage when the comparison shows that the value of the input voltage is less than the lower threshold value.
A method for regulating current, comprising:
- comparing a value of an electrical input voltage to an upper threshold value;
- increasing a value of a correction factor for determining a target variable for the current regulation when a comparison shows that the value of the input voltage is greater than the upper threshold value;
- comparing the value of the electrical input voltage to a lower threshold value;
- and
- reducing the value of the correction factor when the comparison shows that the value of the electrical input voltage is lower than the lower threshold value.
