AnyTrans Transformer Calc

Doesnt work right. I calculated a core that is a huge core and can produce alot of power. This core is high wattage core designed for power transformers but this application rated it at 19.7 watts max power. This app is not good at all. I have anothrr torridial ferrite core the is 63mm x 38mm x 25 mm and this application rates the core at only 9 watts of power. Worthless

Good calculator for existing cores. Bug: once I press Calculate pmax + vturn, the pmax/vturn values are fixed and don't change when I update core parameters. Pressing this button the second time has no effect. I need to close and start again to change core parameters.

Please update EI core transformer theory
