Abstract
Official abstract text for this publication.
In a boost converter operation, a first voltage that is independent of an input voltage of the boost converter is preset in the boost converter, having an increased voltage level compared to the input voltage, as the setpoint output voltage, as long as the input voltage is below a first voltage threshold value, which is lower than the first voltage. As soon as the input voltage exceeds the first voltage threshold value, a second voltage that is a function of the input voltage is preset, having a lower voltage level compared to the input voltage, as the setpoint output voltage. As soon as the input voltage drops below a second voltage threshold value, which is lower than the first voltage, the first voltage is again preset as the setpoint output voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of for operating a boost converter, comprising: setting in the boost converter a first voltage, which is independent of an input voltage of the boost converter and having a higher voltage level than the input voltage, as a setpoint output voltage as long as the input voltage is below a first voltage threshold value which is at lower voltage level than the first voltage; setting in the boost converter a second voltage, which is a function of the input voltage of the boost converter and having a lower voltage level than the input voltage, as the setpoint output voltage as soon as the input voltage exceeds the first voltage threshold value; and setting the first voltage in the boost converter as the setpoint output voltage as soon as the input voltage falls below a second voltage threshold value which is at a lower voltage level than the first voltage. 2. The method as recited in claim 1 , wherein the first and second voltage threshold values are established as a function of the first voltage. 3. The method as recited in claim 2 , wherein the second voltage threshold value is at a lower voltage level than the first voltage threshold value. 4. The method as recited in claim 2 , wherein the second voltage lies below the input voltage by a specified amount.
