Hello,

I look for 60W 1:2 step up transformer. Actually, I dont use a transformer before and I dont know anything about it in practice.
I will use it on the output of my H-bridge circuit to amplify 300Vpp up to 600Vpp. Operating frequency changes between 25khz-45khz. How can I get such a transformer ?

With kind regards,

In your schematics, where you show 300v ac, it cant be from 300v dc. Maximum you can get is below 150v ac.
For transformer core, you need to select size and material of core according to wattage, frequeny and availability. Then select wire and calculate turns to be wound.

Yes, you are right. I wanted to say 300Vac peak to peak. Maybe I can use EI-33 transformer which can be found in computer power supply.
