0.5 v dc dc converter

Belive me if I say that some times I do regret not being a native english; I'm pretty sure I'm missing some subtleties Is this correct?

A AM motor speed controller AC drive. The AC drive the guy is using has an input that ranges from 0 stop to 10 V full speed.

For the moment I have suggested him to solve the problems one by one: to get it working in "manual" position and, then, controlling the whole system by means of the arduino. The "automatic cycle" he intends is pretty much like an old washer machine one: clockwise slow, counterclockwise slow, then medium, then centrifugate,. I've been working with a "due", so one possibility is to use one of the DAC's to generate a "quasi-continuous" signal as Unit suggests.

Then the matter of doubling the range: I have a nice experience on electronics. I'd need a double power supply and I remember adding caps as the Texas Instruments handbook instructed to do to make it stable for a continuous signal. Now it seems there will be a lot of vibrations on this thing so it can't be breadboarded forever.

Yet supposedly there can't be soldering Probably the confirmation that I have to make a small design and, actually, it is not a waste of time.

I'll post the scheme before building it. Probably the op amp circuit will be mounted on a piggy proto card inside the cabinet. Hi, I'm helping a spanish forum guy to build a programmed contrifugal machine. Active 1 year, 7 months ago. Viewed 50 times. Somanna Somanna 8 8 bronze badges. Does the output need to be adjustable? A camera flash circuit is much simpler, usually 3 V to 1. Note how I do not specify a range as that confuses things. Add a comment. Active Oldest Votes. Sign up or log in Sign up using Google.
