Power magnetic component solutions for efficient and reliable electric vehicle chargers

Power magnetic component solutions for efficient and reliable electric vehicle chargers

“The number of fast and superfast electrical car chargers is exponentially increasing. Maximum power density, excellence in thermal management, high reliability components always assuring a cost driven design are the key requirements that the market is demanding. Our solutions are helping EV charger manufacturers meet these requirements”

At Prax we design and manufacture inductive components for power electronics applications, creating added value through customized solutions that help our clients in the industrial and automotive sectors to create reliable and high-quality products.

Prax core competencies are magnetic components and filtering technologies combining a high level of customization possibilities with a comprehensive range of standard components. With a special focus on design support to our customers’ engineering teams, prototypes and specifications are released within a short time frame.

Global customers need global solutions. Besides our outstanding design support, PRAX strives to be a strategic partner by providing global service and support. With a multi-site manufacturing approach, PRAX offers flexible operations, allowing us to establish customized supply chains according to customer requirements.

With our long experience in design and industrialization of inductive components and EMC filters, PRAX offers services based on component specifications, cost analysis, materials selection and pre-industrialization analysis.
