Abstract (en)

[origin: WO9941817A1] The invention relates to devices and methods for regulating parallel-connected voltage transformers, especially in a multi-voltage electric system of an automobile with voltage ranges (U1, U2). The parallel-connected voltage transformers are located between the voltage ranges. A first voltage transformer operates as a main transformer carrying out the guiding function during regulation and the other transformers operate as cascade converters and are connected to the main transformer.
