here is what I'm trying to do.
i want to take my arduino....actually a osepp uno r3 plus
i want to make a 3 phase pwm....
i want the output load load be ac.
i have a circuit that uses 1 phase npn but the ends up going to 2 relays but this is way too slow for the frequency i want and would be very costly to get all those relay
looking for a circuit to work for me

the frequency id around 11k hz
the 3 phase are to get better efficiently
i need pulsed dc + and - 6 volts
so a 12 volt ac

on page 51 is the circuit i want to convert over to the arduino
but the relays are too slow for me
i want the arduino to be the source for the frequency

You linked to a file on your hard drive. To attach it, look to the lower right of the screen and find the "Upload a File" button.

What load are you powering, how many amps or watts? You are starting with DC and want to build a high-frequency, 3-phase inverter. Right? What kind of wave shape do you need, square wave or sine wave?

sorry
I'm looking to max out at approx 12 volts at 25 amps 300 watts
I thought of starting with a dc square wave.
that's what I'm using with my function generator i send that into a driver
i also have infineon n mosfets 065n04ng 7 of them

why.....
testla loved that word as long as it came up with 3
well I've been doing atl. energy for years
refining the art of making gas out of water.
8 ml per watt per min.
so over the years I've learned a few things...
now i need to get this thing automated so that's why the micro
most people look at this as a lost cause... so now i need to get into more electronics

Hi @Drack

That probably wasn't the best introduction. Welcome to AAC!

Do you have the ability to edit your thread title? If you click the edit button on your first post, will it let you enter in a more descriptive thread title? It would be very helpful for those browsing the forums. Many people are turned off by non-descriptive thread names, such as "Please help", "Looking for answers", etc.

Thanks,
Matt

hummmm
not seeing any way to email them....
what would you call this crazy project?
By tagging them in this thread, they will receive a notification and will be called to the thread. All you have to do is choose a new name and they'll fix it for you :)

can you tag someone?
the new title might be like "crazy project 3 phase pwm with bidirectional output"
maybe something like that"

Hello,

If you look at post #12 you'll see that the names are blue and underlined:

upload_2016-1-11_12-31-35.png

That means they have already been tagged. You can tag someone by typing the "@" symbol followed by the exact username.

You have done everything you need to do. Carry on with the thread! :)

You also can click REPORT with your request. That goes directly to a special 'mod place' and any mod on line will see it immediately.
Title changed for you.
Welcome aboard!

cool
why did you pick tesla?
edison still won't pay the 500 dollar bet
I think you mean 50,000 dollar bet :p

Tesla has always been my inspiration. He was way ahead of his time and his focus was on the betterment of mankind, rather than money in his own pocket. The world needs more people like him. Sad thing is a lot of people don't even know his name or what he did for the scientific community.
