Abstract

An electrical system comprised of at least two control modules as well as at least one power supply module. The present invention improves functional reliability of electrical systems by configuring a power supply module as a smart device and connecting it to at least one of the control modules for the purpose of data exchange and, in case of a malfunction, transforming the control module(s) to one of a stand-alone operating mode and a cut-off state.
