Building redundancy in electrical systems that power 400 or 800V electric vehicles

Vicor Corporation converters provide a redundant system by providing an isolated ratio metric frontend that is easily paralleled and a regulator with the built-in paralleling feature.

The traditional DC-DC Converter operating from the 800V battery, creating a 12V isolated, regulated output that is typically a single power train. If any of the power elements in the power train fails, one could lose the 12V, a chemical redundancy (battery) is required so not to disable the vehicle. The 800V battery can be split into two 400V batteries connected in series to support better redundancy.
