DC-DC Converters

Creative Power has developed many multi-kilowatt rated DC to DC converters for a variety of applications. These DC-DC Converter Modules are typically used for voltage manipulation from a variable source to produce a fixed output voltage feeding into a second stage (such as an inverter module).

The example products shown below are all in the 2-5kW range offering either uni-directional or bi-directional power flow to a 650VDC nominal bus.

Creatie Power has also produced non-isolated interleaved boost converters at 25kW, and a 30kW PSSW based naturally cooled step-down DC-DC converter as part of an overall battery charger.

 

Creative Power specializes in the development of custom solutions to meet specific customer requirements. This is achieved through Creative Power's extensive "building blocks" of controllers and power stage designs. Contact us if our listed products don't quite meet your requirements.

The following are examples of some of the products that Creative Power has developed for customers.
