Abstract
A device and a method for detecting a polarity reversal on a low voltage side of a DC voltage transformer in a dual-voltage vehicle electrical system, particularly in a motor vehicle. A current flow is enabled, in this instance, in a connecting line on the low voltage side of the DC voltage transformer by a controllable switching element, a current is detected in a connecting line on the low voltage side of the DC voltage transformer, with the aid of a current sensor system, the direction of the detected current is evaluated by an evaluation unit and a polarity reversal is detected if the direction of the detected current differs from an expected current direction.
