DC/DC Converter For High Power Vehicle Applications

“The D1000 power conversion system is part of our market leading Flexistax series.” Says Tim Worley, CEO of Powerstax. “It has been developed specifically for applications where standard off-the-shelf solutions do not exist. This field proven modular solution offers customers a faster time-to-market, reduced capital investment and minimises the risk often associated with custom designed power supply requirements.

D1000 power solutions are based on the industry leading high power F501 “full-brick” DC:DC Converters that form the core of Powerstax’s business. These patented, ultra-high efficiency and very flexible converters have been designed offer both conventional step-down conversion as well as the more unusual step-up conversion. The key to this is the unique “integrated magnetic” which combines all of the transformers and inductors required by the converter on to one core allowing custom voltage requirements to be provided with ease.

For the D1000 two F501 converters are packaged with connectors as required by the application. In addition, a custom developed boost-converter is integrated into the design to provide input voltage boost when conditions require it. Multiples of D1000 components may be run in N+1 redundant systems.

The D1000 operates from a very wide DC input of 11 to 36V and can be offered with outputs between 12 and 48VDC. The system offers up to 85% efficiency, maximising battery life and reducing thermal management requirements. The complete unit measures a compact 152 x 102 x 25mm. Prototypes can be supplied in just 4 weeks from Powerstax’s ISO9001 approved design, development and production facility in the UK and carry a two year warranty.

Typical applications include military and commercial mobile wireless and radar systems, telecomm infrastructure and security systems.
