Single air gaps are a common technique to delay the core saturation and to increase the power handling capability. However, a single large air gap leads to a high fringing flux effect.
- EPCOS offers a core manufacturing technique of distributed air gaps that significantly reduces the fringing flux effect in order to reduce electromagnetic emissions and heating.
- This technical solution is available or may be manufactured for E, EQ, ER, ETD, PM and PQ cores
- Distributed air gaps are used in the design of power chokes and flyback converters.
- EPCOS is the first manufacturer of ferrite cores with distributed air gaps to provide the marketplace with an economical solution focussing on higher efficiency and downsizing.
