Reverse Polarity on DC Power Supply

[jordanreed]

Hello, I am currently attempting to reverse the polarity from a DC power supply. Basically, I want to create an option in labview which can switch the polarity of a voltage at a given step. I was wondering if there was a way to do this through a DAQ? or should I look at making a whole circuit like an H-Bridge? The application is to a semi-conductive material which behaves differently at different voltages, and when polarity is switched. just trying to automate my test.

Please provide details about the Power supply model and probably a connection circuit. Typically DC Power Supply work only in the first quadrant.

If your power supply is capable of operating in two quadrants, check if it supports automation using Serial/USB/LXI/GPIB. If it does, then you could control this from LabVIEW using appropriate commands.
