What used to take hours of referencing datasheets and solving formulas now takes seconds. You can tweak parameters—like changing the frequency from 50kHz to 100kHz—and instantly see how it changes the required core size. 3. Comprehensive Database
For most users, ExcellentIT_8.0 (from the Yandex link) is the best choice – it includes all bug fixes from the 7300 branch plus a more convenient UI.
is a highly popular, free software application designed for the accurate calculation and design of pulse transformers in push-pull Switched-Mode Power Supplies (SMPS). Developed by Vladimir Denisenko (widely known online as Starichok ), this specific version—7300—stands out in the electronics community because it serves as the ultimate stable release with comprehensive translation support. It allows hobbyists and professional electrical engineers to determine wire diameters, number of turns, and core dimensions without requiring complex manual calculus. Key Features of ExcellentIT-7300
Select the magnetic core shape and material from the integrated database. If using a custom core, you can manually enter the cross-sectional area ( Aecap A sub e ) and magnetic path length ( Lecap L sub e 5. Set the Operating Frequency Excellentit-7300 Download- %21LINK%21
Windows 9x through Windows 10 (32/64-bit); can run on Linux via Wine. Available in both Russian and English. Installation Portable; no installation required (standalone .exe). Typically less than 1 megabyte. Note on Search Queries
: Once the installation is complete, you may be prompted to restart your computer or launch the Excellentit-7300 directly.
If you are using , consider downloading RingFerriteExtraSoft separately, as it adds winding‑layer visualisation and thermal prediction. What used to take hours of referencing datasheets
Sites like Cxem.net Software Directory provide dedicated pages explaining how the software works, interface walkthroughs, and repository access for the various iterations of the program.
Because the software is community-developed, it is best to source it from established electronics forums to ensure you have the latest version:

The program runs on Windows 9x, NT, 2000, XP, Vista, and 7 (both 32‑bit and 64‑bit). With compatibility settings, it also works on Windows 10/11.
Designing Switched-Mode Power Supplies (SMPS) requires precise calculations for transformers and inductors. One of the most revered, albeit older, tools among electronics enthusiasts and power electronics engineers is , specifically the version often referenced as ExcellentIT-7300 or similar early-4000/7000 versions.
Designers of switching mode power supplies (SMPS) often struggle with transformer design. Calculating magnetic core saturation, wire gauge sizes, and winding turns requires absolute precision. A single manual calculation error can destroy your hardware components.
