    Abstract: 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.
