R&D Engineer Power Electronics – HVDC Converter Valve Electrical Design

At Hitachi Energy our purpose is advancing a sustainable energy future for all. We bring power to our homes, schools, hospitals and factories. Join us and work with fantastic people, while learning and developing yourself on projects that have a real impact to our communities and society. Bring your passion, bring your energy, and be part of a global team that appreciates a simple truth: Diversity + Collaboration = Great Innovation
You will be part of Technology and Solutions Development for HVDC applications, within Hitachi Energy in Ludvika. The HVDC technology has been on the market for the past 60 years and is used, among other things, to transmit power over long distances with minimal losses, using overhead lines, underground and submarine cable systems.
The Valve Development Department is a part Technology and Solutions Development office in Ludvika, and it is responsible for the development of new HVDC and SVC converter valves. HVDC converter valves are used to convert AC to DC, and vice versa, and are essential for HVDC power transmissions. SVC converter valves are used in SVC systems, to support and stabilize AC systems. The Valve Development Department is focusing mainly on electrical and mechanical design and development activities and works in close collaboration with the global HVDC organization.
