- a second setting electric power is supplied from the
- High voltage battery 98 transferred to the low-voltage battery 88 to charge them. Further, in a third setting, electrical energy from the external AC power source 54 and / or sink is transferred to both the high voltage battery 98 and the low voltage battery 88 to charge these energy stores. Further, in a fourth setting, electric power is supplied from the
- Low-voltage battery 88 Low-voltage battery 88 and transferred to the public network 54 and fed into this. Further, at a fifth setting, electric power is transmitted from the high-voltage battery 98 to the public network 54, or fed into the public network 54.
- the converter circuit 10 according to the invention is basically not in three
- electromagnetic transmission members 62, 64, 66 limited.
- the electromagnetic transmission unit 60 may also have more transmission members 62, 64, 66 connected to responsive converter circuits for receiving or supplying electrical energy from the transmission unit 60.
- the converter can alternatively be coupled to any direct voltage and / or alternating voltage sources such as solar systems, fuel cells, Quick Charger units or the like, bypassing multi-stage lossy inverter or intermediate converter.
- the Kirpolpolcru 80 can be connected to any voltage networks worldwide.
- the overall principle can also be applied to multiple transformers in order to achieve a high partial load efficiency. Accordingly, the control effort for the control unit 100 would have to be adjusted.
