Finding the Right DC/DC Converter for Iowa State SAE

In summary, the conversation is about finding a DC/DC Converter that can boost 12V DC to 24V DC to power two electromagnetic clutches for a competition. The person is concerned about the reliability of the chosen converters and is seeking input for finding a more reliable and cost-effective option. They also discuss the possibility of revisiting the clutch selection and mention the weight consideration for the converter.

Hey Everyone,

I am working with the Iowa State University SAE and need to find a DC/DC Converter that fits our application. We are running two electromagnetic clutches instead of a traditional differential. So I need to be able to take the regulated 12V DC at 10A from the stator and boost it to 24V DC. Each clutch needs around 2A.

I have noticed a lot of the converters have an on/off functionality and I was considering using two converters so that I can control which clutch/clutches has power.

I have found a couple that appear to fit out application but I am kind of worried about them failing. I am hoping to find something very reliable because if they fail we will basically be out of luck at our competition. (Everyone on the team that drove 36 hours would be pretty upset with me.)

Any input would be greatly appreciated!

p.s. I need to find something on a reasonably short time frame, hopefully I can get a hold of something in the next couple of weeks.

Just curious: Why are you locked into a 24 volt clutch? There are tons of 12 volt clutches out there.

Truthfully I wasn't the one selecting the clutch but from what I understand there were several 12V clutches that we looked at but either price or availability stopped us from acquiring them.

If there is still time, in the interest of cost and reliability, you might want to revisit the clutch selection.

What worries you about your existing choices? I could link to a number of options through standard suppliers but don't know that they would be any better than what you have already selected.

I guess truthfully I am not sure what worries me. This is something I am not really familiar with and I wanted to make sure that I find something that will be very reliable.

This is the only mouser had that seemed to fit our application that wasn't out of stock for the next two months.

The problem is that you need an inexpensive supply. Industrial and military grade supplies this size can run as much as $400-$500.

I thought I had a link for one from Allied, but they didn't have the proper input range for the amp rating. You might scan Allied for any other options.

You might also try checking with Lambda and Sola directly.

Tarmon: Don't forget about the weight! A converter is going to be generally heavy... a lot heavier than not having one xD Every gram makes a difference!

Oh, and we'll see you at competition this year. Good luck :)
