DC-DC DC-DC DC DC DC-DC converter having a transformer and DC network having a DC-DC converter and method to operate a DC network

摘要

The present invention relates to a DC network having a DC-DC converter and a DC-DC converter, and more particularly to a method of operating a DC network with a DC-DC converter, wherein the DC- And a circuit arrangement having two bridge connections with a transformer. The transformer is provided with a step switch that can switch the transformer ratio, and the selection of the transformer ratio can expand the soft switching range of the dual active bridge in the form of a DC-DC converter, The switching loss can be reduced.
