I recall building long ago, a PSU with a unique output able to go up and down between -15V to +15V with a single control. It was used to control a small DC motor.
Recently I tried something but my flawed design, caused excessive heating and I desisted.
What is the right name for it? Adjustable...what? I discard "dual" because that identifies PSUs with coexisting negative and positive rails.
Could anyone lead me to a simple design? Regulated but little power would be OK.
Gracias for any help.
