From customer spec to a manufacturable transformer or inductor — turns, air gap, wire, losses, hotspot — without installing anything.
Faraday turns, Steinmetz core loss with temperature dependence, Dowell AC resistance with porosity correction, Roshen iterative fringing, McLyman area-product core selection, lumped thermal RC — the same equations a textbook designer uses, automated.

Cores, materials, wires and bobbins from leading vendors — calibrated Pcv coefficients, Bsat(T), DC bias curves, AEC-Q200 grading, IEC creepage. Updated periodically.
IEC 62368 creepage / clearance, UL 1446 insulation systems, AEC-Q200 grading, IEC 60664-1 Paschen derate. Designs flagged before they leave the calculator.
No telemetry, no spec uploads, no cloud round-trip. The engine downloads to your tab once and runs on the same RAM your spec lives in. Disconnect after first load — still works.
ISO 7200 spec sheet (Markdown / PDF), IEC 63278 AAS submodel, JEDEC JEP30 PartModel, FEMM Lua script for verification, Tier-A SPICE subcircuit.
The Web Lite architecture serves the engine as a static asset. Your spec, your turns count, your loss numbers — they exist only in this tab. Use it on a flight, in a SCIF, behind an air gap.
Six topology families covered today — LLC, Flyback, Forward, Planar, PFC choke, CM choke.
