Motor vehicle electrical system with two operating voltages

摘要

The invention relates to the electrical system of a motor vehicle with two operating voltages which are supplied by a generator. The system serves generally to increase the power of the vehicle's electrical system. The two operating voltages are supported by one battery each. When the batteries which are connected in series are being charged together, electronic devices for charge compensation are required. These electronic actuating elements can be used in a modified circuit forming an alternating current system.
