Abstract
A power supply device for redundantly supplying power to a load comprises a first supply unit, a second supply unit, a first DC-DC converter, a second DC-DC converter, a first output switching controller, and a second output switching controller. The first and second supply units are interconnected. The first output switching controller is connected on the load side of the first DC-DC converter, and the second output switching controller is connected on the load side of the second DC-DC converter. The outputs of the output switching controllers are interconnected.
Claims18
A power supply device for redundantly supplying power to a load, comprising:
- a first supply unit and a second supply unit, wherein the first and second supply units are interconnected;
- a first DC-DC converter and a second DC-DC converter;
- and
- a first output switching controller and a second output switching controller;
- wherein the first output switching controller is connected on a load side of the first DC-DC converter and the second output switching controller is connected on the load side of the second DC-DC converter;
- wherein the outputs of the first and second output switching controllers are interconnected;
- wherein at least two output switching controllers are connected on the load side of each of the first and second DC-DC converters;
- wherein an additional first output switching controller is connected on the load side of the first DC-DC converter and wherein an additional second output switching controller is connected on the load side of the second DC-DC converter;
- wherein the power supply device further comprises a first switch unit and a second switch unit;
- wherein the output of the first DC-DC converter, the input of the first output switching controller and the output of the additional first output switching controller are routed to the first switch unit of the device;
- wherein the input of the first output switching controller is configured to switch between the output of the first DC-DC converter and the output of the additional first output switching controller using the first switch unit;
- wherein the output of the second DC-DC converter, the input of the second output switching controller and the output of the additional second output switching controller are routed to the second switch unit of the device;
- and
- wherein the input of the second output switching controller is configured to switch between the output of the second DC-DC converter and the output of the additional second output switching controller using the second switch unit.
