Embodiment Construction

[0064] figure 1 A first exemplary embodiment of the circuit arrangement 1 according to the invention is shown. It consists of three magnetically coupled windings W 1 , W 2 and W 3 Transformer T 1 . In the preferred embodiment shown, they can be wound on a common magnetic core. However, this is by no means necessary, and the magnetic coupling can also be realized in other ways. In each case, the first converter ur 1 , the second converter UR 2 and the third converter UR 3 with the three windings W 1 , W 2 and W 3 connected. The first converter UR 1 via the first filter F 1 First connection A to a first power supply for the interior of the motor vehicle or on-board power supply 1 connected. The second converter UR 2 via voltage transformer SW 2 and the second filter F 2 Second connection A to a second power supply for the interior of the motor vehicle or on-board power supply 2 connected. Finally, the third converter UR 3 via voltage transformer SW 3 and ...

Abstract

A circuit arrangement (1) for power distribution in a motor vehicle is described, which comprises a transformer(T 1, T 1a..T 1n )having at least three transformer windings(W 1, W 1a..W 1n, W 2, W 2a..W 2n, W 3, W 3a..W 3n ). A first and second on- board supply inside the vehicle and a power supply which is outside the vehicle can be connected to the circuit arrangement (1), which supplies are coupled via the transformer windings (W 1, W 1a..W 1n, W 2, W 2a..W 2n, W 3, W 3a..W 3n ) and converters(UR 1, UR 2, UR 2a..UR 2n, UR 3, UR 3a..UR 3n ). The third converter (UR 3, UR 3a..UR 3n ) can be connected via a first change-over switch(US 1, US 1 ')alternatively to the first on- board supply inside the vehicle or to the power supply outside the vehicle. Aplurality of first converters(UR 1 ) and/or a plurality of secondconverters(UR 2, UR 2a..UR 2n ) and/or a plurality of thirdconverters(UR 3, UR 3a..UR 3n )each being connected to the transformer windings(W 1, W 1a..W 1n, W 2, W 2a..W 2n, W 3, W 3a..W 3n )can be switched in series or in parallel are provided.

Description

[0001] This application claims priority from, and serves as a formal application of, earlier U.S. Provisional Application No. 61 / 221,028, filed June 26, 2009; this application also claims earlier Swiss National Application No. 61 / 221,028, filed September 1, 2009. Priority of 0982 / 09. The entire contents of Swiss Application No. 0982 / 09 and US Application No. 61 / 221,028 are hereby incorporated by reference, for all intents and purposes, as if equivalently set forth herein. technical field [0002] The present invention relates to a circuit arrangement for power distribution of motor vehicles, more particularly for electric vehicles, said circuit arrangement comprising: [0003] - a transformer having at least three magnetically coupled transformer windings, [0004] - a first connection for a first on-board power supply which is inside the motor vehicle and which is coupled via a first converter to a first transformer winding, [0005] - a second connection for a second on-bo...
