Better cooling and higher frequencies
REO continues to advance the use of EDGE winding technology with the introduction of the latest generation of the N CNW choke and filter series. With increased effectiveness and lower weight at the same time, the new series with high edge winding feature extremely efficient cooling due to their single-layer design – especially when forced cooling is used.
Due to the improved cooling, aluminum conductors can be used as a substitute for copper conductors, depending on the design. In conjunction with automated production, manufacturing costs could therefore be further reduced.
The lower weight and smaller dimensions are possible thanks to the reduction of skin and proximity losses. The EDGE winding is particularly suitable for semiconductors based on new materials such as silicon carbide (SiC) and gallium nitride (GaN).
Due to the lower winding capacitance, the high-cant winding can also be used at higher frequencies. Almost no insulating material is required, so that the service life is increased.
