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.

Powering new generation of aesthetic lasers
The Challenge: New generation of aesthetic lasers require power supplies that can deliver very high peak energy levels to the emitting element with fast energy recovery. These lasers must operate in confined environments and exhibit very low electromagnetic radiation and line disturbances. Additionally, equipment manufacturers are demanding adaptable power solutions that offer advanced monitoring and […]

Powering high demanding MRI with efficiency
The challenge: Magnetic resonance imaging (MRI) uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. The magnetic field generated by the coil is in a range of 2 to 4 Tesla, which is a huge magnetic field with direct effect on some of the […]
