I'm creating a dc to dc booster circuit and I am wondering if it keeps the same frequency going out as coming in to the MOSFET? Even when stepping up the voltage.

 

I don't understand your question. A DC output doesn't have a frequency. Can you post the schematic?

 

Iam using this schematic.

There is a signal going in. Is the same signal going out?

 

The only frequency going on in there is the one you provide, then C5 and C6 do their best to make sure you can't see it on the output.

 

Actually I want it on the output. So is there. Safe way to take out the capacitors and not have a overload.
Or loss in step up voltage.

 

Sounds like you wanna make some sort of voltage amplifier.

What voltage, waveform, frequency and current is your input signal?
What voltage, waveform, frequency and current do you want at the output?

Very dangerous to remove all capacitors because the output voltage will go to hundreds of volts. You will be doing a balancing act with the frequency, capacitance, and the load resistance to get a stable wave shape.

See my blog to learn how the inductor causes very high voltage if the capacitance is too small.

Yes I want it to amplify.

But I also need it to vary in frequency aswell.

I guess there is no real way to do so without a transformer is there?

12v, square, 2-4MHz, no more than ten amps going in.
600v, square, 2-4MHz, no more than .2amps coming out.

 

600v, square, 2-4MHz, no more than .2amps coming out.

That is enough to KILL you !!
As you clearly lack experience in converter circuits, don't even think about building one with this output.

Ok it's enough to kill someone.
But that's not what it's for.
And don't assume I am not experienced enough to understand the dangers.
Or have not taken precautions.

I'm making a table top electroplating system for jewelry.
Yes it can be achieved with lower voltages but for the etching that is required without using acids (safety) requires a higher voltage.
