how to get -200V voltage.

[rain0water]

very less information about the high negative voltage.

i want to power up an op-amp which require +,-200V.
plan to design a boost for the 200V, with +12V power supply.
But no knowledge of the negative side.
any comments?

thanks very much!

Those aren't 2 condensors but power sources in your schematic, right ?
Those 2 = symbols.

edit (sorry; to hasty with submitting)

You have 2 12V dc sources I guess, how do you want to transform them to 200V ?

It would help more to come up with ideas if you explain why you need this and how you want to use it.
I'm guessing in your car, right ? 8)

Can you all the specs of the amp ?

thanks for enquiry. it wouldn't be used in my car, hee....instead, it would be used to drive piezo electric motor.
i plan to build a boost for 200V, it's simple to implement PWM control. easy to achieve.
forget about the shematic, that's just one of my previous thought, but seems not applicable now.
whatever, i really get some info. how to get -200V, because my knowledege on negative voltage is quite limited.

best wishes,
