Aluminum conductors as a replacement for copper conductors
REO continues to advance the use of EDGE Winding technology with the introduction of the latest generation N CNW choke and filter series. With greater effectiveness combined with reduced weight, the new series with edgewise winding boasts extra efficient cooling thanks to its single layer structure, particularly with forced cooling.
Due to better cooling, aluminum conductors may be used as a replacement for copper conductors depending on design. As a result, production costs were able to be reduced even further thanks to the interaction with the automated production process.
The reduced weight and smaller dimensions are possible thanks to the reduction of skin and proximity losses. EDGE Winding is particularly well suited for semiconductors based on new materials like silicon carbide (SiC) and gallium carbide (GaN).
Due to the lower winding capacity, the edgewise winding can also be used at higher frequencies. The life cycle is increased as practically no insulation material is required.
„This edge-winding technology is an innovation from our development team, which is constantly researching the latest technologies and always comes across new approaches as a result. We recognized the opportunities that came with this new winding technology and have been able to start small scale or serial production since 2020, offering our customers extremely fast delivery times. In particular, the impressive cooling feature in the N CNW series is enabled through the single-layer structure with alternative materials meaning little or no insulation material is needed. On the one hand, this results in smaller dimensions and lower weight, and on the other, the product is more durable and there are more applications compared to traditional winding technologies.” Sven Reimann
