discription
|
|
one- or two winding chokes with toroidal core of soft magnetic powder material, wich is pressed.
It is usable for frequencies up to 50 kHz. The toroidal core gives the ideal geometric shape for
the magnetic flux, this results a low magnetic stray field and low losses.
The dimension is determinated from the energy E = 0,5 L I2.
At forced cooling there is less dimension possible. If there is only less over temperature of the choke
allowed, the dimensions must get larger. the winding is constucted for low voltage and is wound with
low stray field.
