Vin_min / V

Vin_max / V

Vin / V for the
calculations

Vout / V

Iout / A

f / kHz

L / H

ΔIL / A
for Vin_max

Proposal

Proposal

N1 / N2
:

The
values of all input fields can be changed.
The proposed value for
L is chosen so that ΔIL=0,4·Iout for
>Vin_max.
The proposed value for
N1/N2 is chosen such that
Vout is just achieved when Vin= Vin_min.

The cores are suggested in such a way that they do not warm up any more to
than approx. 30 K in relation to the ambient.
The wire cross sections are
always suggested for a current density of 3A/mm2

Tip: Its best not to modify
N1/N2 ;-)
