Title: MODULARLY REDUNDANT DC-DC POWER SUPPLY ARRANGEMENT HAVING OUTPUTS THAT CAN BE CONNECTED IN PARALLEL
Abstract:
The invention relates to a power supply arrangement for redundantly supplying power to a load (3), comprising a first supply unit and a second supply unit which are interconnected. The power supply arrangement is designed as a device having a first and a second DC-DC converter (41, 42). A first output switching controller (71) is connected downstream of the first DC-DC converter (41), while a second output switching controller (72) is connected downstream of the second DC-DC converter (42), the outputs of the output switching controllers (71, 72) being interconnected. The redundant power supply arrangement of the invention is designed as a device having two parallel paths, each of which includes two converter stages, thus dispensing with the need to decouple the outputs by means of a redundant circuit.
