Abstract
Systems and/or apparatus are provided for automotive electrical systems having power converters that are coupled by using a transformer. An electrical system comprises a boost converter, wherein a first winding of a transformer is coupled between the input node of the boost converter and a first reference node. The boost converter further includes a switch coupled between the first reference node and a second reference node and a diode coupled between the first reference node and the output node of the boost converter. An energy source is coupled between the input node and the second reference node and a first electrical load is coupled between the output node and the second reference node. The electrical system further comprises a voltage converter having an input coupled to a second winding of the transformer, and a second electrical load coupled to the output of the voltage converter.
