Abstract
The invention relates to a device () for operating a motor vehicle, comprising an electrical drive system with an electrical high-voltage traction network () and an operating network () that has a high-voltage unit () comprising a power electronics system (), and a low-voltage unit () comprising a control electronics system (), and a first transformer () designed to convert an input voltage (U) from the low-voltage unit () into a first, particularly higher output voltage (U) for the power electronics system (). According to the invention, the dev ice comprises at least one second transformer () designed to convert the first output voltage (U) of the first transformer () into a second output voltage (U) for the control electronics system (), the second output voltage (U) being higher than the input voltage (U).
