I need to make a 24V to 500-1000V, 20W adjustable power supply for a pulser.. It needs to be a floating or negative converter.
My specs are:
Input: 24-28V
Output voltage: 500-1000V adjustable via control signal
Output current: 10mA @ 500V (5W), 20mA @ 1000V (20W)
I\'ve been reading through threads on different HV designs. So far the only one I\'ve come across that is isolated is Figure 50 of LT Application Note 29 (https://www.analog.com/media/en/technical-documentation/application-notes/an29f.pdf). It is specified for 1000V, 5W so not beefy enough. The transformer is also obsolete, but this comment mentions potential replacements. https://groups.google.com/d/msg/sci.electronics.design/F120QpxWWkc/74ljdPZ_BQAJ
There\'s also this design (https://www.edn.com/1-kv-power-supply-produces-a-continuous-arc/) that is 1kV, 20W. I just don\'t know enough about making it adjustable and isolated.
Thoughts on how to proceed?
