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.
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.
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.

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 […]
Underwater cables for internet traffic covers long distances and repeaters amplify to keep speed, this demands highly reliable power supplies.
With the multiplication of products transmitting radio signals, it becomes very complex for medical equipment manufacturers to ensure their systems are secured, without interfering or been interfered by other equipment.
