is one of the most reliable and widely used freeware utility tools for calculating switched-mode power supply (SMPS) pulse transformers. Developed by Vladimir Denisenko (widely known in the electronics community as "Starichok"), this light, portable Windows software serves as a core asset for hobbyists, electrical engineers, and DIY power-supply builders.
If the device connects via a USB port or a serial-to-USB adapter, you will need the or CP2102 USB-to-Serial drivers to establish communication between the hardware and your computer.
ExcellentIT-7300 is a calculation suite designed to simplify the complex math involved in designing high-frequency transformers. Unlike standard transformers, pulse transformers used in SMPS require precise calculations for ferrite core saturation, frequency response, and winding topology to ensure efficiency and safety. Core Features: Ensure that the language files (
ExcellentIT is a specialized, freeware Windows application designed to calculate the winding parameters of pulse transformers used in push-pull voltage converters. The "7300" variant is highly sought after because it represents a , making it accessible to international builders who cannot navigate the native Russian interface of alternative versions.
By following this guide, your Excellentit-7300 will provide years of stable, high-performance service. For further help, visit the official Excellentit user forum (forum.excellentit.com) or contact their technical support hotline.
