Guest markdem Posted February 20, 2015 Report Share Posted February 20, 2015 Hi All,I built the 0-30v power supply a few years ago and now would like to rebuild it with the new mods.My idea would be to make 2 of them and make the negative one track the positive giving me a nice dual polarity tracking power supply. Question is, how hard would it be to make it output a negative voltage? Thanks Quote Link to comment Share on other sites More sharing options...
audioguru Posted February 20, 2015 Report Share Posted February 20, 2015 Simply build another power supply completely separate from the first power supply and use its "+" output as 0V and use its "ground" output as its variable negative voltage output.Even the transformer and any meters must be separate.
