Get to know Ocram Power Electronics

Ocram Power Electronics (also known as Ocram), are specialist manufacturers of high voltage diodes, rotating silicon rectifier assemblies, converter assemblies, string diodes and snubbers.

The company was founded in 1999 and worked in partnership with Semikron, one of the Germany’s largest manufacturers of power semiconductors. The team worked hard to develop the entire production line and to introduce cutting-edge innovations.

Today, Ocram offer customers a series of services that run alongside their core business. Amongst these, Ocram has identified that product customisation is key for its customers.

Ocram has been distributing components and assemblies and has solid experience within the energy, aeronautical, naval, electro-medical (laser), wind power, photovoltaic and rail sectors on a worldwide scale. In 2006 Ocram expanded their production capabilities by opening a new operational site in Vicenza, Italy.

Today, Ocram’s products and services are exported all over the world thanks to their extensive distribution network.
