In modern electrical appliances, power electronics assemblies and communications technology elements are often very close together for design reasons. In automotive electronics, EMC problems resulting from this close proximity of data lines and power modules are well known. Consequently, problems with electromagnetic compatibility are best solved at the source, i.e. at the transformers.
Switch mode power supplies use higher and higher frequencies to work with modern GAN FETs (Gallium nitride field effect transistors) efficient power supplies. The probability of interference signals increases. Malfunctions in digital data streams are the result. A well functioning solution is flat wire technology, where the Chinese manufacturer IKP Electronics has a special significance.
Wound goods with flat wire have clear advantages over traditional lacquered round wire windings.
The flat wire has excellent heat dissipation and is suitable for high power and high inductance density applications.
The European EMC Directive defines electromagnetic compatibility as follows:
"the ability of an apparatus, installation or system to operate satisfactorily in the electromagnetic environment without causing electromagnetic disturbance itself which would be unacceptable to any apparatus, installation or system present in that environment.“
These undesirable effects must be counteracted by appropriate technical measures.
