ZVS 'Driverul flybak mazilli
>
Urmatorul driver este departe de cel mai puternic si eficient. ZVS sta pentru 'voltaj zero la comutare', care inseamna fundamental ca atunci cand aici sunt 0v peste mosfet porneste apoi lasa curentul sa treaca,acesta la randul sau cauzeaza o incalzire foarte slaba, pentru exemplu daca ii dai cu 12v. Caldura produsa provine de la tranzistori drenajul non-ideal la sursa, asa ca obtinerea unui mosfet cu RDS foarte mic e importanta, exemple de astfel de MOSFET ar fi irfp250 care este folosit în designul original mazilli. .The 5+5 turns are not cricical, if you wish to power the flyback of a larger voltage you would use more turns and vice-versa.The inductor also is not critical, generaly if one wants more voltage out put he goes for a higher inductance, and if they desire more current a lesser value will do.Now for the capacitor, the 0.68uf has to be a very good quality capacitor like a MKP or and mmc rated at around 300volts. When you have completed the driver and tested at lower voltages lets say 12volts, you can go higher, maybe up to 45volts anything over this and the drain spikes are going to be much higher that the 200v the irfp250 is rated for, so the rule is the mosfets Have to have a VDS (voltage Drain to Source) 4 times higher than the supply voltage.
