The Ferrite Gateway
With increasing demands from power systems and electronic devices with electromechanical elements, such as the movement towards electric vehicles, power and signal transfer on rotating components is becoming increasingly important.
The automotive industry is huge and the technology involved is constantly evolving from the initial “Benz Patent-Motorwagen” first presented in 1886 to the modern day Tesla Model 3 - a lot has happened and the technology involved is significantly different.
Ferrite sheets provide the benefits of traditional soft-magnetic materials whilst providing far more flexibility and versatility, freeing you from the typical mechanical constraints of Ferrite cores. Typically well suited for RFID and EMC protection due to its flexible nature and minimal material thickness (typically less than 0.2mm), Ferrite sheets can also improve the efficiency of wireless power transfer.
As industry evolves and has increasing demands on performance and speed of electronic systems whilst simultaneously reducing costs, these requirements are most noticeable when looking at power transmission. As technology advances a simple solution is actually the answer, using wiring harnesses is becoming a thing of the past and the use of busbars is paving the way for the future of lower cost and higher reliability.
Gateway Electronic Components have been awarded a Silver Senten Manten award from TDK this Autumn in recognition of the company’s unique and differentiated position in the ferrite and power sectors and the contribution made to supply competence and efficiency in the TDK distributor channel.
Ferrite cores and single air gaps are very common as this technique of a single gap is able to delay the core saturation and as a results increase the cores performance. However its not all good as these relatively large single gaps cause higher fringing flux which will lead to additional copper losses in the windings, especially when operating at high frequencies. Now single gaps aren’t bad by any means as the pros out way the cons, however can we improve this technique even further and reduce the cons?
There are lots of manufactures out in the market who say they can undercut the market leaders on price, and even though this may seem to be the most cost-effective option on the day, is that the actual cost that you will pay as a business?
