Onboard electrical network stabilization device for start-stop operation of automobile using secondary energy store for supplying voltage-dependent load during starting

摘要

The network stabilization device has the switch (S1) which connects the starter (S) with the generator (G), the main energy store (1) and the onboard electrical network in the starting mode, also used for connecting the starter with a further series circuit path containing a forwards converter (3), a secondary energy store, a change-over switch (2) and a power distributor (4) for a voltage-dependant load (B). The change-over switch is closed during starting so that the voltage-dependent load is supplied by the main energy store and the secondary energy store.
