OK Mr. Luka
I´m building it, but, I´m with problems with the push pull driver and toroids.... I have a old 1.5 inches outer diameter green color toroid, 1.2cm (Ae), and I don´t know how much (many) gauss it is.
I need calculate the number of turns of this ring core and the other, that mosfet gate driver. My SMPS work only in 127VAC and it´s half bridge, 13VDC output, opto-zener regulated, I need some 20Amps, in this moment is only 5 to 7 Amps and the BUZ73A mosfets (so bad) bang!! OK?!
I waiting by your help
Thank you. |
