"Ouups, can see that I forgot to edit the headline - it's a 600 VDC supply and not a 1000VDC supply."
Hello Forumers,
Hope you can help with this: I am searching for a very low noise ~ 600 VDC power supply. It should have these specifications:
Input: 51VDC +/10 % (if convenient it can be stabilized to e.g. 48 VDC +/- 5 mV)
Output: 600VDC +/- 10% (+/-10% means that it is not crucial whether it is exactly 1000VDC. Also, long-term variations of +/-10% are ok, as long as the period is longer than ~ 5 mins)
Current rating: <10 mA, or, as an alternative 0.1 mA (two different uses)
Start-up time can be < 2 minutes
It must have very, very low levels of short-term voltage variations such as peaks and spikes. What is important is that there are no "sudden" variations in the voltage. Whether it varies in the longer term is less important. Basically short term ripple should be as low as practically possible.
Must be an oscillator, or the like, and not an SMPS
Should be made from components readily available or which can easily be made (e.g. coils etc.). Light-weight, and preferably small-size, and simple![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Any suggestions for diagrams and calculations, or possibly used circuits (??) are appreciated.
