I am trying to build a high frequency step-up transformer for PWM signals.
So Freq 1 and Freq 2 are regulated by the user for a value from 1Hz to 150kHz. The core of the transformer is ferrite, meant for high frequencies.
Then for that I thought that the best solution was a N type MOSFET and use the Freq 1 as Gate and Freq 2 as Drain, but then I found my self with lots of bad planning (newbie) mistakes. So before I go on trying newbie things I though better to get checked my ideas before buying new things to build something that is wrong from the basis. Thanks in advance.
So here I add a circuit with what I think could be the solution, sadly I think is something wrong. I have two MOSFETs because the PWM generator only gives 1-30 mA, which I think is too little to step-up voltage, so I put one MOSFET directly to the 20V that can give about 3 A.
For sure you will have better ideas, I just look for a solution to make this PWM signals with high voltage (from 0V to 300V, or more if possible).
The use of PWM generators or MOSFETs is not mandatory, but both frequencies have to be regulable by user.
