What is that everything?

Primarily this Website was written for people who know the basics of = switchmode power supplies. We did not consider the = control of=20 the transistors, as well as certain preventive measures (discharge = sets,=20 current limitings).
The suggestions for the ferrite cores are=20 approximations based on the manufacturer tables as well as the books=20 Hirschmann/Hauenstein: Schaltnetzteile [1] and Keith Billings: Switch = Mode=20 Power Supply Handbook [2]. Check in any case the specification given by = us with=20 the appropriate data sheets.
