Our scalable DC/DC converter can be used to implement DC power systems consisting of batteries, electric vehicles or photovoltaic systems. It is a buck-boost converter in a single device that can be flexibly configured by software during operation.  Due to dunsere patented technology overlapping voltage ranges at input and output are possible.
