DEVICE FOR CHARGING A BATTERY UNIT AND OPERATING A LOAD UNIT VIA AN INVERTER

The present invention relates to a method and a device for charging a battery unit (10) and operating a load unit (20) via an inverter (30). A first pole (11a) of the battery unit is coupled to an inductive element (22a, 22b, 22c) of the load unit (20) and a voltage tap (51) of an external supply un...

Beschreibung
Zusammenfassung:	The present invention relates to a method and a device for charging a battery unit (10) and operating a load unit (20) via an inverter (30). A first pole (11a) of the battery unit is coupled to an inductive element (22a, 22b, 22c) of the load unit (20) and a voltage tap (51) of an external supply unit (50) is coupled to a first input (37a) of the inverter (30) in order to supply same with an external DC voltage or an external DC current. Further, a switching of the switch elements (31-36) of the inverter (30) is carried out in such a way that the battery unit (10) is supplied with a necessary charging current or a necessary charging voltage from the external supply unit (50) via one of the inductive elements (22a, 22b, 22c).
