Title: BIDIRECTIONAL VEHICLE ELECTRICAL SYSTEM CONVERTER AND METHOD FOR OPERATION THEREOF
Abstract:
The invention is a bidirectional vehicle electrical system converter (10) having an input side for supply of an input voltage, a first current path (14) to at least one connectable load (16) and a second current path (18), in parallel with the first current path (14), from and to a battery (20) and also having an output power converter (80) in the second current path (18), wherein the output power converter (80) can be operated as a rectifier in a charging mode of the vehicle electrical system converter (10) for charging the battery (20) and as an inverter in a feedback mode for supplying power to at least single loads (16), wherein the first and second current paths (14, 18) set out from a secondary side of a transformer (72), wherein the output power converter (80) in the second current path (18) is after the transformer (72) and wherein in feedback mode the output power converter (80) can be used to generate an AC voltage that, by means of the transformer (72), reaches the first current path (14) and at least one load (16) connected thereto.
