Re-design of propulsion system

Railway, Transportation

The challenge
It started with an emergency call from one of our customers. At the first tests of a complete new vehicle the propulsion system stopped at random, and a Powerbox DC/DC converter was suspected to be the cause.

The solution
A Powerbox investigative team was on site the following day, carrying out practical tests and measurements as well as theoretical analysis. The cause was found to be in a subsystem powered from the converter. In certain operational modes this subsystem caused severe overload on the converter, way outside of the design parameters. Our team proposed a solution, by means of a re-design in the subsystem. This was implemented and the project kept on schedule.

Added value
What started off as a warranty complaint changed into electrical design consultancy. This is not an activity we promote, but knowing the expertise is there is comforting – to us and our customers both.
