Hi,
I know we are talking mostly about electronic specified projects here (mostly microcontroller based) but I need a good power source schematic for testing purpose.
Ok, I can try to define the details of circuit I am looking.
I need high voltage variable DC source, it means the output voltage can be vary between 0 and 1000 volts DC and output current must be 5 mA or more at full output voltage. Accuracy is very important, for example I should be set the output voltage to 487 V, and during this period I should be read the current. Measuring systems isn't important because I already have accurate and calibrated equipments. I found some circuits using Fly-back transformer but mostly their output range so high (mostly not variable) and the output has not pure DC. (the ripple factor of output must be loweror equal than 0.01 % because for 1000 V DC 1% ripple factor equal 20 V peak to peak AC signal on my test object and it is not permissible
By the way any other helpful ideas are welcome such as commercial products (must be purchased in Turkey)
Thanks for your help.
