Abstract
The disclosure relates to a method for limiting the starting current of a step-up-converter that is supplied by a DC voltage source. The step-up converter has a first capacitor, a coil connected in parallel to the first capacitor, a second capacitor connected to the coil in series, and a switch connected to the second capacitor in parallel and connected to the coil in series. In a first step, an output voltage of the circuit is measured and the step-up converter is connected to the DC voltage source by closing a power switch that is connected in series to the first capacitor. In a second step, the power switch is opened upon the output voltage increasing by more than a predefined threshold and is maintained open for a predefined time. The first and second steps are repeated until the output voltage reaches a predefined final value.
