Zusammenfassung:	There is provided a transformer circuit 300 for an electric vehicle. The transformer circuit 300 comprises an input 311 for receiving electrical energy; outputs 321, 331, 341 for providing electrical energy to electrical buses of the vehicle at an output voltage; and a transformer 310 disposed between the input and the output. The transformer 310 comprises a primary winding 312 connected to the input and multiple secondary windings 314, 316, 318 connected to the output. The input comprises an AC charging input 330, an ACDC converter 340 configured to receive electrical energy from the AC charging input and provide electrical energy to the primary winding; and a DC charging input 360 arranged between the ACDC converter and the primary winding. The DC charging input (560, Fig. 5) is configured to receive electrical energy from a DC source and provide electrical energy to the primary winding. The converter may have a totem pole topology. The outputs may be connected to vehicle systems including traction batteries or low voltage systems.
