how to get -200V voltage.
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!  ops: ops: |

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 ? - greetz, Vleugels

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, |
