Motor vehicle power supply system for supplying electric motor valve train of internal combustion engine, with electrical energy, has power supply system load directly connected with generator, and connected with battery by control element

摘要

The system (1) has a generator (2) connected with a battery (4), and a power supply system load (5) connected with a battery. Another generator (3) i.e. free-wheel generator, is formed in such a manner that the voltage of the generator is increased with engine speed. Another power supply system load (6) e.g. an electric motor valve train, is directly connected with the generator (3), and is connected with the battery by an electric control element e.g. a diode (8) or semiconductor switch. Switching elements (9) are arranged in series to the diode.
