Redundant voltage supply device

A voltage supply device

• having a first and a second main channel arrangement,
• wherein the first main channel arrangement has a first voltage input (E1) for a first input DC voltage and a first main voltage output (H1) for a first output DC voltage, wherein the first main channel arrangement has a first DC/DC converter device for converting the first input DC voltage into the first output DC voltage, wherein the first DC/DC converter device has a first output inductor which is arranged in series with the first main voltage output (H1),
• wherein the second main channel arrangement has a second voltage input (E2) for a second input DC voltage and a second main voltage output (H2) for a second output DC voltage, wherein the second main channel arrangement has a second DC/DC converter device for converting the second input DC voltage into the second output DC voltage, wherein the second DC/DC converter device has a second output inductor which is arranged in series with the second main voltage output (H2),
• wherein
• the voltage supply device has a first and a second output transformer, wherein the first output inductor is designed as a primary winding of the first output transformer, and the second output inductor is designed as a primary winding of the second output transformer;
• and in that the voltage supply device has at least a first secondary channel arrangement, wherein the first secondary channel arrangement has a first secondary voltage output (N1) and a first secondary winding of the first output transformer and a first secondary winding of the second output transformer,
• wherein the first secondary voltage output (N1) is connected to the first secondary windings which are connected in parallel.
