When calculating the transformer, the operating induction is now used, and not the maximum. The corrected value of the current density for multiple windings, the current is now divided between them. The ad was returned.

Description

From the listing uploaded by “appupdater”.

The app allows you to calculate: - transformers DC-DC converters and HF transformers on ferrite core; - is it possible to wind a transformer or choke on the ring; - dimensions; - inductance and maximum current; - required amount of wire. The result is a theoretical and real course options products you get only by experiment.
