Powerbox’s high efficiency DC/DC converter for light-rail and industrial applications chosen as finalist in prestigious Elektra Awards

News, Pressrelease

Powerbox, one of Europe’s largest power supply companies and a leading force for four decades in optimizing power solutions for demanding applications, has announced that its new ENR500D light rail DC/DC converter has been selected by the Elektra Awards Jury as a finalist in the highly contested Power System Product of the Year category.

“The judges have deliberated, debated and discussed, and this year’s extremely high caliber of entries has yielded a phenomenally strong list of finalists and we are delighted and excited to have reached the shortlist in this hard fought Power System Product of the Year category.” said Patrick Le Fèvre, Chief Marketing and Communication Officer. “Powerbox’s ENR500D light rail DC/DC converter being chosen as a finalist is testimony not only to its high level of innovation but particularly, it is a measure of the forward thinking of Powerbox in developing a power supply that satisfies the needs of light rail and industrial users on a truly world-wide, global basis.”

Dependent upon their world-wide location and the technology available at the time of installation, a wide variety of electrically powered traction systems are used in rapid transit systems. Most metros operate from dc power either at 750VDC with a third rail, or 1.5kV with a third rail or from an overhead catenary. In fact, 750VDC is very common in light rail, powering both the rolling-stock equipment as well as trackside signaling systems. The same voltage is also used in industrial equipment and in applications such as mining.

Taking into account the large range of applications and environmental conditions, PRBX designers had to consider where a power converter would be installed and as such, the environmental conditions it has to withstand. It is in this area that things get difficult for the power supply designer as functional and safety requirements are often a complex blend of design opposites. For example, as specified in the European Standard EN 50124-1, Macro-environmental conditions (PD1 to PD4B), power converters can be part of a hermetically sealed equipment varying from no ventilation up to forced ventilation using clean filtered air from outdoors, and requiring a flexible, robust design able to meet such a large range of environmental conditions.

To meet these strict yet broad requirements, PRBX designers developed a high efficiency 750VDC input DC/DC converter for light-rail and industrial applications. The 500W rated ENR500D platform is built on a resonant topology combined with the latest MOSFET technology and the use of high performance magnetics.

Designed specifically for railway applications, the ENR500D fulfils the aforementioned stringent EN 50124-1 standard and delivers full performance across the temperature range of -40 to +70 degrees C. It is also meets the requirements of the so-called Pollution Degree 2 (PD2) such as control cabinets in the driver’s cabin or passenger compartments.
