I currently have a dual power supply, that supplies +/-15V. One -output of the PS is connected to the other channel's +output (GND). Now, the problem is that I need +/-50V. I bought two step-up boost converters (cheap ones from Amazon), but now I realise that I may have the wrong idea. The converters have +/- input and +/- output, and I connected the +15V from the PS into the +input of one, and -15V into the -input of the other. The unconnected inputs are grounded. Now, my idea was that one of them would give +50V (which it does), and the other -50V. Note that my +converter has its -input and -output grounded, my -converter has its +input and +output grounded.
However, the -50V is not working, and the PS keeps getting current locked. Am I connecting things wrong, or is my idea wrong?
EDIT: Sorry for the confusing explanation. Here is a rough sketch of what I'm trying to do:
I am using this to power a high voltage op-amp, specifically OPA454.
I'm not sure what "isolated" boost converter, but I have two of these from Amazon:
Thanks for all the help.
