Abstract
The present invention relates to a method for determining at least one characteristic parameter of a component of a DC transformer (10) for an on-board electrical network of a motor vehicle (14) using an electronic computing device (16), wherein a first transfer function of a high-voltage-low-voltage DC transformer (12) is determined based on the small-signal behavior of the high-voltage-low-voltage DC transformer (12), and a second transfer function of the DC transformer (10) is determined based on the first transfer function such that the DC transformer (10) has at least one characteristic substantially the same as that of the high-voltage-low-voltage DC transformer (12), and the at least one characteristic parameter of the component of the DC transformer (10) is determined based on the determined second transfer function; the characteristic parameter is determined such that the DC transformer (10) has a step response substantially the same as that of the high-voltage-low-voltage DC transformer (12); and / or the characteristic parameter is determined such that the DC transformer (10) has a Bode plot substantially the same as that of the high-voltage-low-voltage DC transformer (12). The invention also relates to an electronic computing device (16).
